  33
  34 <p><a name="index-README-1"></a>
  35 This is the README file for the distribution of ESS version
  36
  37    <p>5.3.7
  38
  39    <p>ESS is a GNU Emacs and XEmacs mode for interactive statistical programming
  40 and data analysis.  Languages supported: the S family (S 3/4, S-PLUS
  41 3/4/5/6/7, and R), SAS, XLispStat, Stata and BUGS.  Installation help can
  42 be found in sections for both Unix and Windows.  ESS grew out of the desire
  43 for bug fixes and extensions to S-mode and SAS-mode as well as a consistent
  44 union of their features in one package.
  45
  46    <p>The current development team is led by Martin Maechler since August
  47 2004. Former project leader A.J. (Tony) Rossini
  48 (<a href="mailto:rossini@blindglobe.net">rossini@blindglobe.net</a>) did the initial port to
  49 XEmacs and has been the primary coder.  Martin Maechler
  50 (<a href="mailto:maechler@stat.math.ethz.ch">maechler@stat.math.ethz.ch</a>) and Kurt Hornik
  51 (<a href="mailto:Kurt.Hornik@R-project.org">Kurt.Hornik@R-project.org</a>) have assisted with S-PLUS, S4, R, and
  52 XLispStat.  Stephen Eglen (<a href="mailto:stephen@gnu.org">stephen@gnu.org</a>) has worked mostly
  53 on R support.  Richard M. Heiberger (<a href="mailto:rmh@temple.edu">rmh@temple.edu</a>) has
  54 assisted with S-PLUS and S4 development for Windows.  Richard and
  55 Rodney A. Sparapani (<a href="mailto:rsparapa@mcw.edu">rsparapa@mcw.edu</a>) have done much of the work
  56 implementing interactive SAS (i<acronym>ESS[SAS]</acronym><!-- /@w -->) and batch SAS (<acronym>ESS[SAS]</acronym>) support.
  57
  58    <p>We are grateful to the previous developers of S-mode (Doug Bates, Ed Kademan,
  59 Frank Ritter, David M. Smith), SAS-mode (Tom Cook) and Stata-mode (Thomas
  60 Lumley).

 127 <h3 class="section">1.3 New Features</h3>
 128
 129 <p>Changes/New Features in 5.3.7:
 130      <ul>
 131 <li><acronym>ESS</acronym>: <code>ess-default-style</code> now *is* customizable, i.e.,
 132   changing its value in <samp><span class="file">~/.emacs</span></samp> now does have the desired effect.
 133 <li><acronym>ESS</acronym>: <code>ess-font-lock-mode</code> is a new variable (default: t)
 134 which controls whether font-locking is enabled in ESS buffers.
 135 <li><acronym>ESS[R]</acronym>: for XEmacs on Windows; another tweak to find R versions
 136 <li><acronym>ESS[SAS]</acronym>: font-locking updated for ODS and SAS Bayesian Procedures;
 137 a more consistent handling of SAS options by
 138 <code>ess-sas-submit-command-options</code> which is buffer-local; portable
 139 snooze for MS Windows via customize-able <code>ess-sleep-for</code> (floats welcome)
 140 </ul>
 141
 142    <p>Changes/New Features in 5.3.6:
 143      <ul>
 144 <li><acronym>ESS</acronym>: for XEmacs, using &ldquo;gnuclient&rdquo; (without a &ldquo;-q&rdquo;) works for
 145  things like fix() after M-x gnuserv-start has been done.
 146 <li><acronym>ESS[R]</acronym>: M-x R-newest should now work in more situations on MS
 147  Windows, e.g., when R has been installed in a non-default "ProgramFiles"
 148  directory tree.  In these cases, there's no need to specify the name (and
 149  full path) of the R program anymore.
 150 <li><acronym>ESS[R]</acronym>: For XEmacs, startup (with new tooltip code) works again.
 151 </ul>
 152
 153    <p>Changes/New Features in 5.3.5:
 154      <ul>
 155 <li><acronym>ESS[R]</acronym> a new defun is available, <kbd>M-x R-newest</kbd>, which will start
 156 the newest version of R that it can find on your system.
 157 <li><acronym>ESS[R]</acronym> add Sven Hartenstein's &ldquo;R function arguments tips&rdquo;
 158  functionality, via new file <samp><span class="file">../lisp/essd-r-args.el</span></samp>.
 159  Note that this includes an &ldquo;electric "("&rdquo; behavior inside <code>R-mode</code>
 160  which is <em>active by default</em> and can be customized via
 161  <code>ess-r-args-electric-paren</code>; i.e., use <code>(setq
 162  ess-r-args-electric-paren nil)</code> to turn it off.  Further,
 163  <code>ess-r-args-show-as</code> allows to switch to the &ldquo;tooltip&rdquo; mode.
 164 <li><acronym>ESS</acronym>: functions <code>ess-get-pdf-viewer</code> and *-ps-viewer; built on new
 165  customizable variables <code>ess-pdf-viewer-pref</code> and
 166  <code>ess-ps-viewer-pref</code>; currently used in <code>ess-swv-PDF</code> and
 167  <code>*-PS</code>.
 168 <li><acronym>ESS[R]</acronym> Improved <code>ess-swv-PDF</code> to run pdf viewer only if
 169  pdflatex was ok
 170 <li><acronym>ESS[R]</acronym> Improved <code>ess-swv-weave</code> to start R automatically if
 171  none is running.
 172 <li><acronym>ESS</acronym>: Do no longer ask <em>which</em> ESS process to use if there
 173  is only one.
 174 </ul>
 175
 176    <p>Changes/New Features in 5.3.4:
 177      <ul>
 178 <li><acronym>ESS[R]</acronym> now better work with options(error=recover); and the
 179 new default of CHM help files on windows.
 180 <li><acronym>ESS[R]</acronym> some more cleanup in the &ldquo;sweave&rdquo; functions
 181 <li>miscellaneous fixes
 182 </ul>
 183
 184    <p>Changes/New Features in 5.3.3:
 185      <ul>
 186 <li><acronym>ESS[S]</acronym> fix buglet (5.3.2 only) which left command prompt in
 187 &ldquo;execute buffer&rdquo; and hence help files.
 188 <li>new customizable variable <code>ess-display-buffer-reuse-frames</code>
 189 set to true (which changes default behavior) such that execution or
 190 help *frames* are reused.
 191 </ul>
 192
 193    <p>Changes/New Features in 5.3.2:
 194      <ul>
 195 <li>Classic BUGS now supported by <code>(require 'essd-bugs)</code> with <acronym>ESS[BUGS]</acronym>
 196       and JAGS by <code>(require 'essd-jags)</code> with <acronym>ESS[JAGS]</acronym>.  But, only one
 197       of them can be used at a time since they don't play nice together.  Also,
 198       <kbd>C-c C-c</kbd> is now bound to the function <code>ess-bugs-next-action</code>
 199       (<kbd>F12</kbd> has been retired).  And finally, note that <samp><span class="file">essl-bug.el</span></samp>
 200       is deprecated and the replacement is <samp><span class="file">essl-bugs.el</span></samp>.
 201 <li><acronym>ESS[R]</acronym> Improved some of the &ldquo;Sweave-make&rdquo;
 202  functions (yet scarcely documented) in <samp><span class="file">ess-swv.el</span></samp>.
 203 <li><acronym>ESS[S]</acronym> No longer mess with .Last.value (nor in other &ldquo;languages&rdquo;).
 204 </ul>
 205
 206    <p>Changes/New Features in 5.3.1:
 207      <ul>
 208 <li>See the docs for 2 ways to install <acronym>ESS</acronym> for XEmacs
 209           <ol type=1 start=1>
 210       <li>by uncommenting the XEmacs part of
 211             Section 1 of <samp><span class="file">Makeconf</span></samp> and performing <code>make install</code>
 212       <li>by unpacking either
 213             <samp><span class="file">ess-5.3.1.tgz</span></samp> or <samp><span class="file">ess-5.3.1.zip</span></samp> into
 214             <samp><span class="file">PREFIX/lib/xemacs/site-packages</span></samp> on unix or
 215             <samp><span class="file">PREFIX\XEmacs\site-packages</span></samp> on windows
 216           </ol>
 217 <li><acronym>ESS[R]</acronym>: fixed bugs so that Rterm.exe can be found by XEmacs
 218 <li><acronym>ESS[S]</acronym>: <kbd>ess-toggle-S-assign-key</kbd> is slightly changed; in
 219  particular, the default <code>ess-assign-key</code> is now <kbd>C-x =</kbd>.
 220 <li><acronym>ESS[R]</acronym>: <kbd>M-x R-site-search</kbd> is a new (slightly experimental)
 221  utility similar to R's <code>RSiteSearch(..)</code> but with the advantage of
 222  using Emacs' preferred browser, see <code>browse-url-browser-function</code>
 223 </ul>
 224
 225    <p>Changes/New Features in 5.3.0:
 226      <ul>
 227 <li><acronym>ESS[BUGS]</acronym>: sanely re-format statistical output, <samp><span class="file">.bog</span></samp>,
 228 from scientific notation to numbers rounded with 4 decimal places
 229 with <kbd>M-x ess-bugs-sci-round-to-4-dp</kbd>.
 230 <li>The keys for navigating among section headings in help buffers
 231 worked, but only for one language per session; they should now work for
 232 multiple languages.  (They were also broken on Windows machines.)
 233 <li><acronym>ESS[S]</acronym> long standing buglets in the internal logic for loading
 234 lisp code on Windows.  Particularly fixed behavior in help mode with S-plus
 235 GUI.
 236 <li>New variable, <code>ess-use-inferior-program-name-in-buffer-name</code>,
 237 which enables using the executable name instead of the dialect name for
 238 R. Feature request.
 239 <li><acronym>ESS[S]</acronym> <kbd>ess-execute-screen-options</kbd>
 240 now also works correctly when there is more than one window *side-by-side*
 241 in the same frame and runs in the correct buffer also when there is more
 242 than one S buffer.
 243 <li>i<acronym>ESS[S]</acronym><!-- /@w --> new functions <code>ess-eval-paragraph-and-step</code> and
 244  <code>ess-eval-function-or-paragraph-and-step</code> are bound to keys
 245  <kbd>C-c C-p</kbd> and <kbd>C-c C-c</kbd> respectively and to the menu in
 246  <acronym>ESS</acronym>-mode; also bound in the help mode (for evaluating examples).
 247 <li><acronym>ESS[S]</acronym> new function <code>ess-toggle-S-assign-key</code> allows to
 248 assign the &ldquo; &lt;- &rdquo; insertion to an arbitrary key.
 249 </ul>
 250
 251    <p>Changes/New Features in 5.2.12:
 252      <ul>
 253 <li><acronym>ESS[SAS]</acronym>: <kbd>M-;</kbd> fixed, but the XEmacs function <code>comment-dwim</code>
 254 may be broken, if so, use <kbd>M-x comment-region</kbd> and <kbd>M-x
 255 uncomment-region</kbd> instead; only valid PROCs are fontified which is very
 256 helpful finding syntax errors (currently supported: BASE, ETS, FSP, GRAPH,
 257 IML, INSIGHT and STAT); the &ldquo;feature&rdquo; where <kbd>F</kbd>-keys take you to an
 258 empty buffer when the requested destination is a file that does not exist
 259 has been fixed, now the request results in a no-op.
 260 Further, sas-mode now also works in simple terminals.
 261 <li>Rterm/Cygwin combination works under Microsoft Windows.
 262 <li><acronym>ESS[R]</acronym>: internal calls use baseenv() instead of NULL and
 263 define 'baseenv' where needed.
 264 <li>New experimental support for installing ESS.  See the file
 265 <samp><span class="file">lisp/ess-install.el</span></samp>.
 266 </ul>
 267
 268    <p>Changes/New Features in 5.2.11:
 269      <ul>
 270 <li>ESS Info entry and <samp><span class="file">dir</span></samp> handled more effectively for GNU Emacs users
 271 <li><acronym>ESS[SAS]</acronym>: temporary files created for batch submission of a
 272 region are now named based on the current file; see <code>ess-sas-file-root</code>
 273 for details; all <code>lag</code> and <code>dif</code> functions now fontified correctly
 274 <li>iESS[SAS]: fixed a few nagging bugs, however, still does not appear to
 275 work at this time; please let us know if you have any ideas.
 276 <li><acronym>ESS[S]</acronym>: Support for running other versions of Splus has been
 277 added for unix.  Two new variables, <code>ess-s-versions</code> and
 278 <code>ess-s-versions-list</code>, are used to tell ESS what other versions of
 279 Splus you would like to run.
 280 </ul>
 281
 282    <p>Changes/New Features in 5.2.10:
 283      <ul>
 284 <li><acronym>ESS[R]</acronym>: ess-r-versions can no longer be customized (since the
 285 customization was not taking effect unless customizations were loaded
 286 before ESS).  Its value has been changed so that it will also find R
 287 executables beginning &ldquo;R-devel&rdquo; and &ldquo;R-patched&rdquo;.  If you wish to
 288 change this variable, it must be set in your <samp><span class="file">.emacs</span></samp> before ESS is
 289 loaded.
 290 <li>Installation with GNU Make enhanced:  unix and unix-like
 291 operating systems will now be able to install <acronym>ESS</acronym> for all
 292 users in either a GNU Emacs site-lisp or an XEmacs package
 293 configuration by editing <samp><span class="file">lisp/ess-site.el</span></samp> and <samp><span class="file">Makeconf</span></samp>
 294 accordingly, then issuing <code>make install</code>
 295 <li><acronym>ESS[S]</acronym>: Filename completion (inside strings) now also works in
 296 XEmacs for R and S-plus.
 297 <!-- working around a bug in XEmacs -->
 298 </ul>
 299
 300    <p>Changes/New Features in 5.2.9:
 301      <ul>
 302 <li><acronym>ESS[R]</acronym> for Windows:  the \ directory character bug
 303 with respect to ess-load-file has been eradicated.
 304 <li>i<acronym>ESS[SAS]</acronym><!-- /@w -->: <kbd>C-c C-r</kbd> and <kbd>C-c C-b</kbd> once again
 305 work as intended and documented.
 306 <li><acronym>ESS[S]</acronym>: M-x ess-fix-EQ-assign is a bit more agressive.
 307 <li><acronym>ESS[S]</acronym>: Imenu now also shows setAs(), etc.
 308 <li><acronym>ESS[R]</acronym>: R function pattern enhanced with underlying code such that
 309  <kbd>M-C-a</kbd> (<code>ess-beginning-of-function</code>) etc now work for many more
 310  cases, including S4 method definitions.
 311 <li>i<acronym>ESS[R]</acronym><!-- /@w -->: myOwnhelp(1) no longer wrongly triggers help(1).
 312 <li><acronym>ESS[R]</acronym>: Improved detection of bogus help buffers: valid help
 313  buffers containing with the string &ldquo;no documentation&rdquo;(e.g. contour)
 314  were being treated as bogus.
 315 <li><acronym>ESS[R]</acronym>: In R help buffers, if <code>options("help.try.all.packages" =
 316  TRUE)</code> then <code>?rlm</code> will list which packages rlm is defined in.  This help
 317  buffer is not bogus, but instead is now relabelled &ldquo;*help[R](rlm in
 318  packages)*&rdquo;.
 319 <li><acronym>ESS[STA]</acronym>: add &ldquo;//&rdquo; as comment starting character to syntax-table.
 320 </ul>
 321
 322    <p>Changes/New Features in 5.2.8:
 323      <ul>
 324 <li>iESS: [Tab] completes <strong>file</strong> names &ldquo;inside string&rdquo; as in
 325 earlier (&lt;= 5.2.3) ESS versions.
 326 </ul>
 327
 328    <p>Changes/New Features in 5.2.7:
 329      <ul>
 330 <li>If you use Custom to change the variable ess-toolbar-items,
 331 the new toolbar is used in all subsequent ESS buffers.
 332 <li><acronym>ESS[SAS]</acronym>: new feature:  if ess-sas-log-max &gt;0 and
 333 your .log grows to more than ess-sas-log-max bytes, just
 334 the first ess-sas-log-max bytes are refreshed; this is helpful when your .sas program
 335 generates lots of error messages and gets too big for emacs to display
 336 <li><acronym>ESS[R/S]</acronym>: <kbd>M-;</kbd> in R/S editing modes will now indent with
 337 either one or two hashes depending on context.
 338 <li><acronym>ESS[R]</acronym>: David Whiting's Sweave extensions (to 'noweb')
 339 are now available (from ess-swv.el loaded by default).
 340 </ul>
 341
 342    <p>Changes/New Features in 5.2.6:
 343      <ul>
 344 <li>Removed non-ASCII characters in a few files.
 345 <li><acronym>ESS[R]</acronym>: now works better when UTF-8 locale is active; in
 346  particular, you get correct directional quotes in R's startup message
 347  for R-devel (unstable development version of R 2.1.0) when using
 348  environment variables LANGUAGE=en@quot LC_ALL=en_US.UTF-8
 349 <li><acronym>ESS[SAS]</acronym>: toggling of .log mode improved (<kbd>F10</kbd>); toggling of
 350 .lst mode now also available (<kbd>C-F10</kbd>); killing all buffers associated
 351 with .sas program no longer bound to <kbd>C-F10</kbd> since its a bit overzealous.
 352 <li>S-Plus 7 for Windows is now recognized.
 353 <li><acronym>ESS[S]</acronym> (incl. R): in auto-fill mode, strings are not wrapped anymore.
 354 <li><acronym>ESS[S]</acronym> (incl. R): font-lock now correctly differs between R and S,
 355 e.g., for "_"; both now fontify warning(.) and S does terminate() additionally.
 356 <li>Support for `bell' aka `beep' aka `ding' aka `alarm' in all inferior
 357 modes: When \a is output &ldquo;to the the console&rdquo; at the beginning of a line,
 358 the bell is rung.
 359 </ul>
 360
 361    <p>Changes/New Features in 5.2.5:
 362      <ul>
 363 <li><acronym>ESS[R]</acronym>: <kbd>C-c C-q</kbd> or `<samp><span class="samp">Quit S</span></samp>' from the menu now should work
 364 (again and less klunkily) and do not append `<samp><span class="samp">-exited</span></samp>' to the
 365 buffer name.  Further, the behavior of <code>(ess-cleanup)</code>, called from
 366 ess-quit, now depends on the new customizable variable
 367 <code>ess-S-quit-kill-buffers-p</code> which defaults to <code>nil</code>.
 368 Consequently, the question <em>&ldquo;Delete all buffers associated
 369 with ..?&rdquo;</em> will not be asked anymore by default.
 370 <li><acronym>ESS[SAS]</acronym> &ndash; ess-ebcdic-to-ascii-search-and-replace will now work
 371 with the <code>recode</code> application as well which is available on many platforms
 372 <li><acronym>ESS[S]</acronym> (incl. R): Name completion for slots of S4 objects now works!
 373 </ul>
 374
 375    <p>Changes/New Features in 5.2.4:
 376      <ul>
 377 <li>The documentation now includes an overview of how to use the emacs
 378 TAGS facility for S functions.  (The distribution also used to contain a
 379 directory <samp><span class="file">etc/other/Tags</span></samp> where a ~1990 version of <samp><span class="file">etags.c</span></samp> was
 380 distributed; this is no longer relevant and so has been deleted.)
 381 <li><acronym>ESS[SAS]</acronym> &ndash; When you are working with EBCDIC files on an ASCII
 382 platform, .log NOTEs may display as gibberish since the EBCDIC
 383 characters are not converted to ASCII prior to their display.  So,
 384 the function ess-ebcdic-to-ascii-search-and-replace is provided for
 385 convenience and is bound to <kbd>C-F11</kbd>.  This function requires the
 386 <code>dd</code> command (only available on unix or unix-like platforms).
 387 <li>ESS: Completion of object names is now always done dynamically rather
 388 than allowing the option of using a pre-computed database (by
 389 <code>ess-create-object-name-db</code>) since modern computers seem fast
 390 enough for dynamic completion.  (We expect few users, if any, have
 391 been using the pre-computed database method.)
 392 <li>ESS: object completion in iESS buffers running on Windows was
 393 very slow (for GNU Emacs, but not XEmacs) and has now been fixed.
 394 Further, it was more or less broken for all versions of S-plus 6.x,
 395 and has been fixed to work everywhere but with the Windows' GUI of
 396 S-plus.  The list of objects now shows unique names also when an
 397 object appears more than once in the search path.
 398 <li><acronym>ESS[R]</acronym>: Completion of object names now also includes those
 399 starting with &ldquo;.&rdquo;.
 400 </ul>
 401
 402    <p>Changes/New Features in 5.2.3:
 403      <ul>
 404 <li>ESS: When new inferior ESS processes are created, by default they
 405 will replace the current buffer (this restores behavior from pre
 406 5.2.0). If you wish new ESS processes to start in another window of the
 407 current frame, set inferior-ess-same-window to nil.
 408 <li>New variables inferior-Splus-args and inferior-R-args provide a
 409 way to pass command line arguments to starting S and R processes.
 410 </ul>
 411
 412    <p>Changes/New Features in 5.2.2:
 413      <ul>
 414 <li>bug-fixes for 5.2.1 (require 'executable), html docs, etc.
 415 <li>ess-lisp-directory/../doc/info added to Info-directory-list
 416 if ess-info not found by info
 417 <li><acronym>ESS[R]</acronym>: If you have other versions of R on your
 418 exec-path, such as "R-1.8.1" with Unix or "rw1081" with Windows,
 419 ESS will find them and create appropriate functions, such as
 420 <kbd>M-x R-1.8.1</kbd> or <kbd>M-x rw1081</kbd>, for calling them.
 421 By default only Unix programs beginning "R-1" and
 422 "R-2" and Windows programs parallel to the
 423 version of R in your exec-path will be found,
 424 but see ess-r-versions and ess-rterm-versions for ways to find other
 425 versions of R.
 426 <li><acronym>ESS[R]</acronym>: Other versions of R, such as "R-1.8.1" on Unix and "rw1081" on
 427 Windows, are added to the
 428 "ESS / Start Process / Other" menu.
 429 <li><acronym>ESS[S]</acronym>: If you have other versions of S-Plus on your Windows computer,
 430 such as S-Plus 6.1 or S-Plus 4.5, ESS will find them and create appropriate
 431 functions, such as <kbd>M-x splus61</kbd>, for calling the console version (Sqpe)
 432 inside an emacs buffer.  By default only
 433 programs installed in the default location will be found, but see
 434 ess-SHOME-versions for ways to find other versions of S-Plus.
 435 <li><acronym>ESS[S]</acronym>: Other versions of Sqpe on Windows, such as "splus61",
 436 are added to the
 437 "ESS / Start Process / Other" menu.
 438 <li><acronym>ESS[R]</acronym>: (bug fix) ess-quit (bound to <kbd>C-c C-q</kbd>) should now quit the
 439 inferior R process, when issued from either the inferior buffer, or from
 440 a .R buffer.
 441 </ul>
 442
 443    <p>Changes/New Features in 5.2.1:
 444      <ul>
 445 <li><acronym>ESS[S]</acronym> (R and S-plus): now have toolbar support
 446 with icons to evaluate code in the inferior process or to switch
 447 there.  This code is experimental and likely to change as XEmacs/Emacs
 448 issues get resolved. The toolbar should be enabled if your Emacs
 449 displays images, but can be disabled with the variable ess-use-toolbar.
 450 Thanks to David Smith from Insightful for the S-plus logo.
 451 <li><acronym>ESS[SAS]</acronym>: ess-sas-graph-view (<kbd>F12</kbd>) enhanced; you can specify
 452 external file viewers for each graphics file type via the alist
 453 ess-sas-graph-view-viewer-alist; also .jpg/.gif are now handled
 454 by image-mode on XEmacs, if available, otherwise by graphics
 455 primitives as before
 456 </ul>
 457
 458    <p>Changes/New Features in 5.2.0:
 459      <ul>
 460 <li><acronym>ESS[BUGS]</acronym>:  new info documentation!  now supports interactive
 461 processing thanks to <a href="mailto:Aki.Vehtari@hut.fi">Aki Vehtari</a>;
 462 new architecture-independent unix support as well as support for BUGS v. 0.5
 463 <li><acronym>ESS[SAS]</acronym>:  convert .log to .sas with ess-sas-transcript;
 464 info documentation improved; Local Variable bug fixes;
 465 SAS/IML statements/functions now highlighted; files edited
 466 remotely by ange-ftp/EFS/tramp are recognized and pressing
 467 SUBMIT opens a buffer on the remote host via the local variable
 468 ess-sas-shell-buffer-remote-init which defaults to "ssh";
 469 changed the definition of the variable ess-sas-edit-keys-toggle
 470 to boolean rather than 0/1; added the function ess-electric-run-semicolon
 471 which automatically reverse indents lines containing only "run;";
 472 <kbd>C-F1</kbd> creates MS RTF portrait from the current buffer;
 473 <kbd>C-F2</kbd> creates MS RTF landscape from the current buffer;
 474 <kbd>C-F9</kbd> opens a SAS DATASET with PROC INSIGHT rather than PROC FSVIEW;
 475 "inferior" aliases for SAS batch:  <kbd>C-c C-r</kbd> for submit region,
 476 <kbd>C-c C-b</kbd> for submit buffer, <kbd>C-c C-x</kbd> for goto .log; <kbd>C-c C-y</kbd> for goto .lst
 477 <li><acronym>ESS[S]</acronym>: Pressing underscore ("_") once inserts " &lt;- " (as before);
 478 pressing underscore twice inserts a literal underscore.  To stop this
 479 smart behaviour, add "(ess-toggle-underscore nil)" to your .emacs after
 480 ess-site has been loaded;
 481 ess-dump-filename-template-proto (new name!) now can be
 482 customized successfully (for S language dialects);
 483 Support for Imenu has been improved; set ess-imenu-use-S to non-nil to
 484 get an "Imenu-S" item on your menubar;
 485 ess-help: Now using nice underlines (instead of `nuke-* ^H_')
 486 <li><acronym>ESS[R]</acronym>:  After (require 'essa-r), <kbd>M-x ess-r-var</kbd> allows to load
 487 numbers from any Emacs buffer into an existing *R* process;
 488 <kbd>M-x ess-rdired</kbd> gives a &ldquo;directory editor&rdquo; of R objects;
 489 fixed ess-retr-lastvalue-command, i.e. .Last.value bug
 490 (thanks to David Brahm)
 491 <li>ESS: Support for creating new window frames has been added to
 492 ESS.  Inferior ESS processes can be created in dedicated frames by
 493 setting inferior-ess-own-frame to t.  ESS help buffers can also open in
 494 new frames; see the documentation for ess-help-own-frame for details.
 495 (Thanks to Kevin Rodgers for contributing code.)
 496 </ul>
 497
 498    <p>Changes/New Features in 5.1.24:
 499      <ul>
 500 <li>The version number is now correct even inside ESS/Emacs
 501 </ul>
 502
 503    <p>Changes/New Features in 5.1.23:
 504      <ul>
 505 <li>Minor more Makefile clean up.
 506 </ul>
 507
 508    <p>Changes/New Features in 5.1.22:
 509      <ul>
 510 <li>Besides info documentation, PDF and HTML
 511 documentation are also provided (instead of built using "make") and available
 512 on the web as well; see <a href="http://ess.r-project.org/">ESS web page</a> and <a href="http://lib.stat.cmu.edu/general/ESS/doc">StatLib</a>
 513 <li>Now that info documentation is available, the
 514 README.* files are no longer supported.  However, they
 515 are still distributed for what it's worth.
 516 <li>ESS is now an XEmacs package!  See
 517 <a href="http://www.xemacs.org/Install/index.html">XEmacs Installation HOWTO</a>
 518 for details (specifically, items 10-15).
 519 <li><acronym>ESS[SAS]</acronym>: more user-friendly enhancements for remote
 520 SAS batch jobs with Kermit file transfers (LOG and OUTPUT
 521 function key features now supported).  Multiple shells
 522 now supported so you can run SAS on different computers
 523 from different buffers by setting the buffer-local variable
 524 ess-sas-shell-buffer to unique buffer names.
 525 <li>Major re-vamping of Makefile/Makeconf.
 526 </ul>
 527
 528    <p>Changes/New Features in 5.1.21:
 529      <ul>
 530 <li><acronym>ESS[SAS]</acronym>: info documentation now available!, see
 531 ESS-&gt;Help for SAS; <kbd>F12</kbd> opens GSASFILE nearest point for viewing
 532 either within emacs, when available, or via an external viewer;
 533 more syntax highlighting keywords; more enhancements for remote
 534 SAS batch jobs with Kermit; new framework for remote SAS interactive
 535 jobs, see ess-remote
 536 <li><acronym>ESS[S]</acronym>: info documentation now available!, see
 537 ESS-&gt;Help for the S family
 538 <li>Makefile: tag now independent of rel; info files
 539 made by doc/Makefile and installed in new info sub-directory
 540 </ul>
 541
 542    <p>Changes/New Features in 5.1.20:
 543      <ul>
 544 <li>New `options()$STERM' in the S dialects (S, S-Plus, R).
 545 The S program can determine the environment in which it is
 546 currently running.  ESS sets the option to `iESS' or `ddeESS'
 547 when it starts an S language process.  We recommend other specific
 548 values for S language processes that ESS does not start.
 549 <li>New `ess-mouse-me' function, assigned to S-mouse-3 by default.
 550 User may click on a word or region and then choose from the
 551 menu to display the item, or a summary, or a plot, etc.
 552 This feature is still under development.
 553 <li>GNU Emacs 21.1 is now supported (fixed for S dialects, SAS &amp; BUGS),
 554 (some from Stephen Eglen).
 555 <li>XEmacs 21.x is now supported (fixed w32-using-nt bug)
 556 <li>XEmacs on Win (NT) is better supported.
 557 <li>Workaround for bug in Sqpe+6 (S-PLUS 6 for Win).
 558 <li>should now work even when imenu is not available (for old XEmacsen).
 559 <li><acronym>ESS[SAS]</acronym>: XEmacs-Imenu fix; <kbd>C-TAB</kbd> is globalized along with your
 560 function-key definitions, if specified; you can specify your SAS
 561 library definitions outside of autoexec.sas for ess-sas-data-view
 562 with SAS code placed in the variable ess-sas-data-view-libname,
 563 also the dataset name is defaulted to the nearest permanent dataset
 564 to point; Speedbar support now works for permanent datasets, please
 565 ignore first./last.; new font-locking is now the default with more
 566 improvements for font-locking PROCs, macro statements, * ; and %* ;
 567 comments; you can toggle sas-log-mode with <kbd>F10</kbd> which will font-lock
 568 your .log (if it isn't too big); submit remote .sas files accessed
 569 with ange-ftp, EFS or Tramp (Kermit is experimental) by setting
 570 ess-sas-submit-method to 'sh; ess-sas-submit-command and
 571 ess-sas-submit-command-options are buffer-local so you can have
 572 local file variable sections at the end of your .sas files to
 573 request different executables or specify special options and the
 574 local file variables are re-read at submit instead of only at file
 575 open so that if you make a change it is picked up immediately;
 576 <li><acronym>ESS[BUGS]</acronym>: font-lock with `in' fixed.
 577 <li>for STATA: font-lock bug fixed.
 578 <li>for Rd mode: <kbd>C-c C-v</kbd> and `switch-process' in menu.
 579 further, <kbd>C-c C-f</kbd> prefix (Rd-font) for inserting or surrounding a word
 580 by things such as \code{.}, \code{\link{.}}, \emph{.} etc.
 581 <li>new functions (ess-directory-function) and (ess-narrow-to-defun)
 582 ess-directory &lt;-&gt; default-directory logic (Jeff Mincy).
 583 <li>Re-organized Makefile and fixed a few bugs.
 584 </ul>
 585
 586    <p>Changes/New Features in 5.1.19:
 587      <ul>
 588 <li>S+6 now supported (Tony Rossini (Unix) and Rich Heiberger (Windows))
 589 <li>New BUGS support through <acronym>ESS[BUGS]</acronym> mode (Rodney Sparapani)
 590 Templates assist you in writing .bug and .cmd code (.cmd and .log
 591 are replaced by .bmd and .bog to avoid emacs extension collisions).
 592 Substitution" parameters facilitate "automagic" generation of
 593 data...in" and "init...in" filenames, "const N=" from your data
 594 file and "monitor()/stats()" commands.  Activated by pressing <kbd>F12</kbd>.
 595 <li>Fixes for `ess-smart-underscore' SAS breakage (Rich Heiberger)
 596 <li>You can change between PC and Unix, local and global SAS function-key
 597 definitions interactively (Rich Heiberger)
 598 <li><kbd>C-Submit</kbd> a highlighted region to SAS batch (Rodney Sparapani)
 599 <li>New and improved SAS syntax highlighting (Rodney Sparapani)
 600 To get the new functionality, set ess-sas-run-make-regexp to nil.
 601 Also available in .log files via <kbd>F10</kbd>.
 602 <li>Open a permanent SAS dataset for viewing via <kbd>F9</kbd> (Rodney Sparapani)
 603 You must have the library defined in autoexec.sas for it to work.
 604 <li>User-friendly defaults for `sas-program', `ess-sas-batch-pre-command'
 605 and `ess-sas-batch-post-command' as well Customize support for these
 606 and other <acronym>ESS[SAS]</acronym> variables (Rodney Sparapani)
 607 <li>`ess-sas-suffix-2' now defaults to .dat via <kbd>F11</kbd> (Rodney Sparapani)
 608 <li>Emacs/XEmacs, Unix/Windows issues collectively handled in ess-emcs.el
 609 <li>defadvice solves problem of missing *ESS* (thanks to Jeff Mincy)
 610 <li>Improved manual a bit by including things that were only in `README'.
 611 </ul>
 612
 613    <p>Changes/New Features in 5.1.18:
 614      <ul>
 615 <li>New `ess-smart-underscore' function, now assigned to "_" by default.
 616 Inserts `ess-S-assign' (customizable " &lt;- "), unless inside string
 617 and comments where plain "_" is used instead. (MM)
 618 <li>Fixes for longstanding interactive SAS breakage (RMH)
 619 </ul>
 620
 621    <p>Changes/New Features in 5.1.17:
 622      <ul>
 623 <li>Documentation for Windows Installation (Rich Heiberger)
 624 <li>removal of ess-vars, finalization of customize support (in the
 625 sense that there is no more use of ess-vars, but that we need to
 626 fix ess-cust) (AJ Rossini)
 627 <li>Many small (and large) fixes/contributions (MMaechler)
 628 <li>addition of the "S-equal" variable and provide <kbd>M-x ess-add-MM-keys</kbd>
 629 a way to remap "_" to `ess-S-assign', typically " &lt;- ", but
 630 customizable. (MMaechler)
 631 </ul>
 632
 633    <p>Changes/New Features in 5.1.16:
 634      <ul>

 642 </ul>
 643
 644    <p>Changes/New Features in 5.1.14:
 645      <ul>
 646 <li>Yet more fixes to SAS mode, (Rich Heiberger and Rodney Sparapani)
 647 <li>Customize support (for most Emacsen which support it) (AJRossini)
 648 <li>ARC and ViSta support out of the box, and fixes for XLispStat (AJRossini)

 660 <li>Splus 5.1 stabilized, thanks to Martin Maechler, Bill Venables,
 661 Chuck Taylor, and others.
 662 <li>More fixes to SAS mode, thanks to Rodney Sparapani
 663 and Rich Heiberger.
 664 </ul>
 665
 666    <p>Changes/New Features in 5.1.11:
 667      <ul>
 668 <li>More fixes to Stata mode, thanks to
 669 <a href="mailto:brendan@essex.ac.uk">Brendan Halpin</a>.
 670 <li>fixed bugs in ESS-elsewhere, thanks to many testers
 671 <li>README.SPLUS4WIN has DETAILED instructions for S-PLUS 2000, thanks
 672 to <a href="mailto:brahm@alum.mit.edu">David Brahm</a>.
 673 <li>Fixes to SAS mode, thanks to Rodney Sparapani
 674 </ul>
 675
 676    <p>Changes/New Features in 5.1.10:
 677      <ul>
 678 <li>More fixes to Stata mode
 679 <li>primitive generic version of ESS-elsewhere
 680 <li>Small fixes to SAS/Stata.
 681 </ul>
 682
 683    <p>Changes/New Features in 5.1.9:
 684      <ul>
 685 <li>Stata mode works
 686 <li>Literate Data Analysis using Noweb works

 688
 689    <p>Changes/New Features in 5.1.8:
 690      <ul>
 691 <li>Bug fixes
 692 <li>R documentation mode defaults changed
 693 </ul>
 694
 695    <p>Changes/New Features in 5.1.2:
 696      <ul>
 697 <li>able to use inferior iESS mode to
 698 communicate directly with a running S-Plus 4.x process using the
 699 Microsoft DDE protocol.  We use the familiar (from Unix ESS) <kbd>C-c C-n</kbd>
 700 and related key sequences to send lines from the S-mode file to the
 701 inferior S process.  We continue to edit S input files in <acronym>ESS[S]</acronym> mode
 702 and transcripts of previous S sessions in ESS Transcript mode.  All
 703 three modes know the S language, syntax, and indentation patterns and
 704 provide the syntactic highlighting that eases the programming tasks.
 705 </ul>

 836 <h3 class="section">1.7 Getting the Latest Version</h3>
 837
 838 <p>The latest released version of ESS is always available on the web at:
 839 <a href="http://ess.r-project.org">ESS web page</a> or
 840 <a href="http://lib.stat.cmu.edu/general/ESS/">StatLib</a>
 841
 842 <!-- There no longer is an anonymous CVS repository for ESS, due to lack of -->
 843 <!-- interest, little demand, and problems with security. -->
 844 <!-- text below modified from R-admin.texi (thanks to Kurt for the tip). -->
 845 <p>The latest development version of ESS is available via
 846 <a href="https://svn.R-project.org/ESS/">https://svn.R-project.org/ESS/</a>, the ESS Subversion repository.  If
 847 you have a Subversion client (see <a href="http://subversion.tigris.org/">http://subversion.tigris.org/</a>),
 848 you can download the sources using:
 849 <pre class="smallexample">     % svn checkout https://svn.r-project.org/ESS/trunk <var>path</var>
 850 </pre>
 851    <p class="noindent">which will put the ESS files into directory <var>path</var>.  Later,
 852 within that directory, `svn update' will bring that directory up to
 853 date.  Windows-based tools such as TortoiseSVN are also available for
 854 downloading the files.  Alternatively, you can browse the sources with a
 855 web browser at: <a href="https://svn.r-project.org/ESS/trunk">ESS SVN site</a>.  However, please use a subversion client instead to minimize the
 856 load when retrieving.
 857
 858    <p>If you remove other versions of ESS from your emacs load-path, you can
 859 then use the development version by adding the following to .emacs:
 860
 861 <pre class="example">     (load "/path/to/ess-svn/lisp/ess-site.el")
 862 </pre>
 863    <p>Note that https is required, and that the SSL certificate for the
 864 Subversion server of the R project is
 865
 866 <pre class="smallexample">     Certificate information:

 902      <li>
 903 <code>cd</code> to a directory where you keep emacs lisp files, or create a
 904 new directory (for example, <samp><span class="file">$HOME/emacs</span></samp>) to hold the distribution.
 905 This directory will be referred to below as "the ESS distribution
 906 directory".
 907
 908      <p><em>Note for XEmacs packages:</em> ESS is no longer available as an XEmacs package.
 909 But, you can still install ESS into the XEmacs package system by choosing
 910 <samp><span class="file">ESSDIR</span></samp>=<samp><span class="file">PREFIX/lib/xemacs/site-packages</span></samp>.
 911 ESS requires that the XEmacs sumo tarball (all XEmacs packages combined) also
 912 be installed.  For information on installing XEmacs packages, follow this link:
 913 <a href="http://www.xemacs.org/Documentation/packageGuide.html">Quickstart Package Guide</a>.
 914
 915      <!-- It will contain, -->
 916 <!-- at the end, the tar file @file{ess-VERSION.tar.gz}, and a directory for -->
 917 <!-- the ESS source, which will be termed "the ESS-VERSION source directory". -->
 918 <!-- Note that the .elc files may be installed elsewhere (as specified in the -->
 919 <!-- Makefile) if desired. -->
 920 <li>Retrieve the latest version from
 921 <a href="http://ess.r-project.org/downloads/ess">ESS downloads area</a>
 922 to <samp><span class="file">ESSDIR</span></samp>.
 923
 924      <li>Extract the files from the disribution.
 925      <pre class="display">          If you are using GNU tar, <code>tar zxf ess-VERSION.tgz</code>.
 926           Otherwise, <code>gunzip &lt; ess-VERSION.tgz | tar xf -</code>,
 927      </pre>
 928      <p>The <code>tar</code> command will create the subdirectory <samp><span class="file">ess-VERSION</span></samp> and install
 929 the files there.
 930
 931      <!-- If you are using GNU Emacs 19.29, decompress/unarchive -->
 932 <!-- @file{ESSDIR/ess-VERSION/lisp/19.29.tar.gz}, -->
 933 <!-- read @file{ESSDIR/ess-VERSION/lisp/19.29/README}, follow the instructions -->

 935 <!-- @emph{Please note that GNU Emacs 19.29 is no longer supported}. -->
 936 <!-- For a list of supported versions of emacs, see @xref{Requirements}. -->
 937 <li>Edit the file <samp><span class="file">ESSDIR/ess-VERSION/lisp/ess-site.el</span></samp> as explained in the
 938 comments section of that file.
 939 <!-- Installations that are using ESS only for S-Plus -->

 941 <!-- have one or more of (S4, S+3/4/5/6/7/8, R, SAS, BUGS, XLispStat, Stata) -->
 942 <!-- may need to uncomment corresponding lines in @file{ESSDIR/ess-VERSION/lisp/ess-site.el}. -->
 943
 944      <li>If you are using GNU Emacs add the line
 945      <pre class="example">          (load "ESSDIR/ess-VERSION/lisp/ess-site")
 946      </pre>
 947      <p>to <samp><span class="file">$HOME/.emacs</span></samp>.  For XEmacs, if you followed the XEmacs package system
 948 installation advice, add the line
 949      <pre class="example">          (require 'ess-site)
 950      </pre>
 951      <p>to <samp><span class="file">$HOME/.xemacs/init.el</span></samp>.  Otherwise, for XEmacs, add the line

 960 <!-- @example -->
 961 <!-- (require 'ess-site) -->
 962 <!-- @end example -->
 963 <!-- to configure emacs for ESS. -->
 964 <li>That's it!  ESS is now ready to use.  (The remaining step below is only for a
 965 custom installation.)  To edit statistical programs, just open files with the
 966 requisite extensions (<samp><span class="file">.R</span></samp> for R, <samp><span class="file">.sas</span></samp> for SAS, <samp><span class="file">.bug</span></samp> for BUGS,
 967 etc.).  To start a statistical process within emacs, such as R, type <code>M-x R</code>.
 968
 969      <!-- @item -->
 970 <!-- (OPTIONAL) If you are running S-PLUS or R, you might consider -->
 971 <!-- installing the database files.  From within emacs, @code{C-x d} to the -->
 972 <!-- directory containing ESS.  Now: -->
 973 <!-- @example -->
 974 <!-- M-x S+6 -->
 975 <!-- @end example -->
 976 <!-- to get S running.  Once you see the SPLUS prompt, do: -->
 977 <!-- @example -->
 978 <!-- M-x ess-create-object-name-db -->
 979 <!-- @end example -->
 980 <!-- (this will create the file @file{ess-sp6-namedb.el}; if it isn't in the -->
 981 <!-- ESS directory, move it there). -->
 982 <!-- Then, completions will be autoloaded and will not be regenerated for -->
 983 <!-- every session. -->
 984 <!-- For R, do the same, using -->
 985 <!-- @example -->
 986 <!-- M-x R -->
 987 <!-- @end example -->
 988 <!-- and then @code{M-x ess-create-object-name-db} creating -->
 989 <!-- @file{ess-r-namedb.el}; if it isn't in the ESS directory, move it there). -->
 990 <li><b>(OPTIONAL) READ THIS ITEM THOROUGHLY BEFORE STARTING</b>:
 991
 992      <p>If you want to place the compiled files in other locations edit the
 993 <code>LISPDIR</code>, <code>INFODIR</code> and <code>ETCDIR</code> entries in Section 1 of
 994 <samp><span class="file">Makeconf</span></samp> in the <samp><span class="file">ESSDIR/ess-VERSION</span></samp> directory (if you are
 995 using XEmacs, then uncomment the XEmacs subsection in Section 1).
 996
 997      <p>You can compile those files by:
 998      <pre class="example">          make all
 999      </pre>
1000      <p>When that completes successfully, install the compiled files:
1001      <pre class="example">          make install
1002      </pre>
1003      <!-- This will install the compiled info files and lisp files.  If you are an -->
1004 <!-- XEmacs user, then you should be done.  If not, then you may have to -->
1005 <!-- edit/create the file @file{dir} that is found in the directory specified -->
1006 <!-- by @code{INFODIR}: see the sample @file{dir} in ESSDIR/ess-VERSION/doc/info. -->
1007 <!-- If @file{dir} does not exist in @code{INFODIR}, then the sample -->
1008 <!-- @file{dir} will be installed. -->
1009 <!-- An alternative, if you are running XEmacs and have access to the -->
1010 <!-- XEmacs system directories, would be to place the directory in the -->
1011 <!-- site-lisp directory, and simply type @code{make all} (and copy the -->
1012 <!-- documentation as appropriate). -->
1013 <!-- For GNU Emacs, you would still have to move the files into the top level -->

1031 <p>For <b>Microsoft Windows installation</b>, please follow the next steps.
1032
1033      <ol type=1 start=1>
1034
1035      <li><code>cd</code> to a directory where you keep emacs lisp files, or create a
1036 new directory (for example, <samp><span class="file">c:\emacs\</span></samp>) to hold the distribution.
1037 This directory will be referred to below as "the ESS distribution
1038 directory".
1039
1040      <p><em>Note for XEmacs packages:</em> ESS is no longer available as an XEmacs
1041 package. But, you can still install ESS into the XEmacs package system
1042 by choosing <samp><span class="file">ESSDIR</span></samp>=<samp><span class="file">PREFIX\XEmacs\site-packages</span></samp>.  ESS
1043 requires that the XEmacs sumo tarball (all XEmacs packages combined)
1044 also be installed.  For information on installing XEmacs packages,
1045 follow this link:
1046 <a href="http://www.xemacs.org/Documentation/packageGuide.html">Quickstart Package Guide</a>.
1047
1048      <li>Retrieve the latest zip file (<samp><span class="file">ess-VERSION.zip</span></samp>) from
1049 <a href="http://ess.r-project.org/downloads/ess">ESS downloads area</a> and
1050 store it in the ESS distribution directory.  Be aware that http browsers
1051 on Windows frequently change the "." and "-" characters in filenames to
1052 other punctuation.  Please change the names back to their original form.
1053
1054      <li>Extract all the files from <samp><span class="file">ess-VERSION.zip</span></samp> into the ESS
1055 distribution directory as <samp><span class="file">c:\emacs\ess-VERSION\</span></samp>.  (It is possible
1056 to unpack the zip archive in Windows Explorer by double clicking on the
1057 folder; you should then see a new folder called <samp><span class="file">ess-VERSION</span></samp>.
1058 Drag that folder into your ESS distribution directory.)
1059
1060      <!-- @item -->
1061 <!-- Add the line -->
1062 <!-- @example -->
1063 <!-- (load "C:/emacs/ess-VERSION/lisp/ess-site") -->
1064 <!-- @end example -->
1065 <!-- to your emacs initialization file.  (GNU Emacs uses the filename -->
1066 <!-- @file{~/.emacs} and XEmacs uses the filename -->
1067 <!-- @file{~/.xemacs/init.el} for the initialization file.  The tilde is -->
1068 <!-- recognised by emacs as your HOME directory, i.e. the value of your HOME -->
1069 <!-- environment variable.)  Replace -->
1070 <!-- @code{VERSION} above with the version number of ESS.  Remember to use -->
1071 <!-- forwardslashes @code{/}, rather than backslashes @code{\}, in your filename -->
1072 <!-- inside emacs code files. -->
1073 <li>If you are using GNU Emacs add the line
1074      <pre class="example">          (load "ESSDIR/ess-VERSION/lisp/ess-site")
1075      </pre>
1076      <p>to <samp><span class="file">%HOME%/.emacs</span></samp>.  For XEmacs, if you followed the XEmacs package system
1077 installation advice, add the line
1078      <pre class="example">          (require 'ess-site)
1079      </pre>
1080      <p>to <samp><span class="file">%HOME%/.xemacs/init.el</span></samp>.  Otherwise, for XEmacs, add the line
1081      <pre class="example">          (load "ESSDIR/ess-VERSION/lisp/ess-site")
1082      </pre>
1083      <p>to <samp><span class="file">%HOME%/.xemacs/init.el</span></samp>.
1084 <em>Note:</em> Both GNU Emacs and XEmacs require that the HOME environment
1085 variable be set on your system, otherwise, your initialization file will
1086 not be utilized, and therefore, ESS will not work.
1087
1088      <p>After saving your initialization file, ESS is now installed.  Start a
1089 new emacs and you should be ready to use ESS.  For example, to edit
1090 statistical programs, load the files with the requisite extensions
1091 (".sas" for SAS, ".S" or "s" or "q" or "Q" for S-PLUS, ".r" or ".R" for
1092 R, and ".lsp" for XLispStat).  One further step is needed if you wish to
1093 run statistical processes, see below.
1094
1095      <li>To run statistical processes under ESS, Windows users will need to make
1096 sure that the directories for the software they will be using is in the
1097 PATH environment variable.  On Windows 9x, add lines similar to the
1098 following to your <samp><span class="file">c:\autoexec.bat</span></samp> file:
1099      <pre class="example">          path=%PATH%;c:\progra~1\insightful\splus70\cmd
1100      </pre>
1101      <p>On Windows NT/2000/XP, add the directories to the PATH using the
1102 <code>My Computer/Control Panel/System/Advanced/Environment Variables</code> menu.
1103 Note that the directory containing the program is
1104 added to the PATH, not the program itself.  One such line is needed
1105 for each software program.  Be sure to use the abbreviation
1106 <code>progra~1</code> and not the long version with embedded blanks.  Use
1107 backslashes "<code>\</code>".
1108
1109      <p>An alternative, for R users, is that rather than adjusting the PATH
1110 variable, you can add the following to your emacs initialization file
1111 (and restart emacs):
1112      <pre class="example">          (setq inferior-R-program-name "C:/progra~1/R/R-2.2.1/bin/Rterm.exe")
1113      </pre>
1114      <p>This assumes that you have installed R-2.2.1 in the default location.
1115 Change the path otherwise to point to other locations.
1116
1117      <p>Windows users who place S-PLUS anywhere other than the default
1118 location will also need to add the following three lines (properly
1119 adjusted for their location) to their <samp><span class="file">%HOME%/.emacs</span></samp> or
1120 <samp><span class="file">%HOME%/.xemacs/init.el</span></samp> file:
1121      <pre class="example">          (setq-default inferior-S+6-program-name
1122               "c:/progra~1/Insightful/SPLUS70/cmd/Splus")
1123           (setq-default inferior-Sqpe+6-SHOME-name
1124               "c:/progra~1/Insightful/SPLUS70")
1125           (setq-default inferior-Sqpe+6-program-name
1126               "c:/progra~1/Insightful/SPLUS70/cmd/Sqpe.exe")
1127      </pre>
1128      <p>The above example uses the default location of S-PLUS in
1129 <code>c:/progra~1/Insightful</code>.  Please note that ESS
1130 considers S-PLUS 6, 7, and 8 to be variants of S+6.
1131
1132      <p>These users may also need to modify the emacs variable <code>ess-SHOME-versions</code>
1133 to match their installation in order to get the full set of S-PLUS versions
1134 on their machine into the <code>ESS</code> menu.
1135
1136      <p>To start the S-PLUS [678].x GUI from ESS under emacs:
1137           <ol type=1 start=1>
1138 <li>If you use Cygwin bash as your primary shell, then
1139           <pre class="example">               M-x S
1140                (or <code>M-x S+6</code>).
1141           </pre>
1142           <li>If you use the MSDOS prompt window as your primary shell, then
1143           <pre class="example">               M-x S+6-msdos
1144           </pre>
1145           </ol>
1146 You will then be
1147 asked for a pathname ("S starting data directory?"), from which to
1148 start the process.  The prompt will propose your current directory
1149 as the default.  ESS will start the S-PLUS GUI.  There will be
1150 slight delay during which emacs is temporarily frozen.  ESS will arrange for
1151 communication with the S-PLUS GUI using the DDE protocol.
1152 Send lines or regions
1153 from the emacs buffer containing your S program (for example,
1154 <samp><span class="file">myfile.s</span></samp>) to the S-PLUS Commands Window with the
1155 <code>C-c C-n</code> or <code>C-c C-r</code> keys.
1156 (If you are still using S-PLUS 4.x or 2000,\
1157 then use <code>M-x S+4</code> or <code>M-x S+4-msdos</code>.)
1158
1159      <p>To start an S-PLUS [678].x session inside an emacs buffer&mdash;and
1160 without the S-PLUS GUI:
1161      <pre class="example">          M-x Sqpe
1162           (or <code>M-x Sqpe+6</code>).
1163      </pre>
1164      <p>This works with both the bash and msdos shells.
1165 You will then be asked for a pathname ("S starting data
1166 directory?"), from which to start the process.  The prompt will
1167 propose your current directory as the default.
1168 You get Unix-like behavior, in particular the entire
1169 transcript is available for emacs-style search commands.
1170 Send lines or regions from the emacs buffer containing your S
1171 program (for example, <samp><span class="file">myfile.s</span></samp>) to the *S+6* buffer with the
1172 <code>C-c C-n</code> or <code>C-c C-r</code> keys.
1173 Interactive graphics are available with Sqpe by using the java
1174 library supplied with S-PLUS 6.1 and newer releases.
1175 Enter the commands:
1176      <pre class="example">          library(winjava)
1177           java.graph()
1178      </pre>
1179      <p>Graphs can be saved from the <code>java.graph</code> device
1180 in several formats, but not PostScript.   If you
1181 need a PostScript file you will need to open a separate
1182 <code>postscript</code> device.
1183 (If you are still using S-PLUS 4.x or 2000, then use <code>M-x Sqpe+4</code>.)
1184
1185      <p>To connect to an already running S-PLUS GUI (started, for example,
1186 from the S-PLUS icon):
1187      <pre class="example">          M-x S+6-existing
1188      </pre>
1189      <p>or
1190      <pre class="example">          M-x S+6-msdos-existing
1191      </pre>
1192      <p>You will then be
1193 asked for a pathname ("S starting data directory?"), from which to
1194 start the process.  The prompt will propose your current directory
1195 as the default.  ESS will arrange for
1196 communication with the already running S-PLUS GUI using the DDE protocol.
1197 Send lines or regions
1198 from the emacs buffer containing your S program (for example,
1199 <samp><span class="file">myfile.s</span></samp>) to the S-PLUS Commands Window with the
1200 <code>C-c C-n</code> or <code>C-c C-r</code> keys.
1201 (If you are still using S-PLUS 4.x or 2000,
1202  then use <code>M-x S+4-existing</code> or <code>M-x S+4-msdos-existing</code>.)
1203
1204      <p>If you wish to run R, you can start it with:
1205      <pre class="example">          M-x R
1206      </pre>
1207      <p>XLispStat can not currently be run with
1208      <pre class="example">          M-x XLS
1209      </pre>
1210      <p>Hopefully, this will change.  However, you can still edit with
1211 emacs, and cut and paste the results into the XLispStat
1212 *Listener* Window under Microsoft Windows.

1268
1269 <p>Please send bug reports, suggestions etc. to
1270 <a href="mailto:ESS-bugs@stat.math.ethz.ch">ESS-bugs@stat.math.ethz.ch</a>
1271
1272    <p>The easiest way to do this is within Emacs by typing
1273
1274    <p><kbd>M-x ess-submit-bug-report</kbd>
1275
1276    <p>This also gives the maintainers valuable information about your
1277 installation which may help us to identify or even fix the bug.
1278
1279    <p>If Emacs reports an error, backtraces can help us debug the problem.
1280 Type "M-x set-variable RET debug-on-error RET t RET".  Then run the
1281 command that causes the error and you should see a *Backtrace* buffer
1282 containing debug information; send us that buffer.
1283
1284    <p>Note that comments, suggestions, words of praise and large cash
1285 donations are also more than welcome.

1297 <h3 class="section">1.12 Mailing Lists</h3>
1298
1299 <p>There is a mailing list for discussions and announcements relating to
1300 ESS.  Join the list by sending an e-mail with "subscribe ess-help" (or
1301 "help") in the body to <a href="mailto:ess-help-request@stat.math.ethz.ch">ess-help-request@stat.math.ethz.ch</a>;
1302 contributions to the list may be mailed to
1303 <a href="mailto:ess-help@stat.math.ethz.ch">ess-help@stat.math.ethz.ch</a>.  Rest assured, this is a fairly
1304 low-volume mailing list.
1305
1306    <p>The purposes of the mailing list include
1307
1308      <ul>
1309 <li> helping users of ESS to get along with it.
1310 <li> discussing aspects of using ESS on Emacs and XEmacs.
1311 <li> suggestions for improvements.
1312 <li> announcements of new releases of ESS.
1313 <li> posting small patches to ESS.
