1 1 General Information: README
2 *****************************
4 This is the README file for the distribution of ESS version
8 ESS is a GNU Emacs and XEmacs mode for interactive statistical
9 programming and data analysis. Languages supported: the S family (S
10 3/4, S-PLUS 3/4/5/6/7, and R), SAS, XLispStat, Stata and BUGS.
11 Installation help can be found in sections for both Unix and Windows.
12 For INSTALLATION, see way below.
14 ESS grew out of the desire for bug fixes and extensions to S-mode and
15 SAS-mode as well as a consistent union of their features in one package.
17 The current development team is led by Martin Maechler since August
18 2004. Former project leader A.J. (Tony) Rossini
19 (<rossini@blindglobe.net>) did the initial port to XEmacs and has been
20 the primary coder. Martin Maechler (<maechler@stat.math.ethz.ch>) and
21 Kurt Hornik (<Kurt.Hornik@R-project.org>) have assisted with S-PLUS,
22 S4, R, and XLispStat. Stephen Eglen (<stephen@gnu.org>) has worked
23 mostly on R support. Richard M. Heiberger (<rmh@temple.edu>) has
24 assisted with S-PLUS and S4 development for Windows. Richard and
25 Rodney A. Sparapani (<rsparapa@mcw.edu>) have done much of the work
26 implementing interactive SAS (iESS[SAS]) and batch SAS (ESS[SAS])
29 We are grateful to the previous developers of S-mode (Doug Bates, Ed
30 Kademan, Frank Ritter, David M. Smith), SAS-mode (Tom Cook) and
31 Stata-mode (Thomas Lumley).

46 1.2 Starting an ESS process
47 ===========================
49 To start an S session on Unix or on Windows when you use the Cygwin
50 bash shell, simply type `M-x S RET'.
52 To start an S session on Windows when you use the MSDOS prompt
53 shell, simply type `M-x S+6-msdos RET'.
58 Changes/New Features in 5.2.13:
59 * New variable, `ess-use-inferior-program-name-in-buffer-name',
60 which uses the executable name instead of the dialect name for R.
63 * ESS[S] `ess-execute-screen-options' now also works correctly when
64 there is more than one window *side-by-side* in the same frame and
65 runs in the correct buffer also when there is more than one S
68 * iESS[S] new functions `ess-eval-paragraph-and-step' and
69 `ess-eval-function-or-paragraph-and-step' are bound to keys `C-c
70 C-p' and `C-c C-c' respectively.
72 * ESS[S] new function `ess-toggle-S-assign-key' allows to assign the
73 " <- " insertion to an arbitrary key.
75 * ESS[S] long standing bugs in ess-help for Windows (S-plus GUI)
78 Changes/New Features in 5.2.12:
79 * ESS[SAS]: `M-;' fixed, but the XEmacs function `comment-dwim' may
80 be broken, if so, use `M-x comment-region' and `M-x
81 uncomment-region' instead; only valid PROCs are fontified which is
82 very helpful finding syntax errors (currently supported: BASE,
83 ETS, FSP, GRAPH, IML, INSIGHT and STAT); the "feature" where
84 `F'-keys take you to an empty buffer when the requested
85 destination is a file that does not exist has been fixed, now the
86 request results in a no-op. Further, sas-mode now also works in
89 * Rterm/Cygwin combination works under Microsoft Windows.
91 * ESS[R]: internal calls use baseenv() instead of NULL and define
92 'baseenv' where needed.
94 * New experimental support for installing ESS. See the file
95 `lisp/ess-install.el'.
97 Changes/New Features in 5.2.11:
98 * ESS Info entry and `dir' handled more effectively for GNU Emacs
101 * ESS[SAS]: temporary files created for batch submission of a region
102 are now named based on the current file; see `ess-sas-file-root'
103 for details; all `lag' and `dif' functions now fontified correctly
105 * iESS[SAS]: fixed a few nagging bugs, however, still does not
106 appear to work at this time; please let us know if you have any
109 * ESS[S]: Support for running other versions of Splus has been added
110 for unix. Two new variables, `ess-s-versions' and
111 `ess-s-versions-list', are used to tell ESS what other versions of
112 Splus you would like to run.
114 Changes/New Features in 5.2.10:
115 * ESS[R]: ess-r-versions can no longer be customized (since the
116 customization was not taking effect unless customizations were
117 loaded before ESS). Its value has been changed so that it will
118 also find R executables beginning "R-devel" and "R-patched". If
119 you wish to change this variable, it must be set in your `.emacs'
120 before ESS is loaded.
122 * Installation with GNU Make enhanced: unix and unix-like operating
123 systems will now be able to install ESS for all users in either a
124 GNU Emacs site-lisp or an XEmacs package configuration by editing
125 `lisp/ess-site.el' and `Makeconf' accordingly, then issuing `make
128 * ESS[S]: Filename completion (inside strings) now also works in
129 XEmacs for R and S-plus.
131 Changes/New Features in 5.2.9:
132 * ESS[R] for Windows: the \ directory character bug with respect to
133 ess-load-file has been eradicated.
135 * iESS[SAS]: `C-c C-r' and `C-c C-b' once again work as intended and
138 * ESS[S]: M-x ess-fix-EQ-assign is a bit more agressive.
140 * ESS[S]: Imenu now also shows setAs(), etc.
142 * ESS[R]: R function pattern enhanced with underlying code such that
143 `M-C-a' (`ess-beginning-of-function') etc now work for many more
144 cases, including S4 method definitions.
146 * iESS[R]: myOwnhelp(1) no longer wrongly triggers help(1).
148 * ESS[R]: Improved detection of bogus help buffers: valid help
149 buffers containing with the string "no documentation"(e.g. contour)
150 were being treated as bogus.
152 * ESS[R]: In R help buffers, if `options("help.try.all.packages" =
153 TRUE)' then `?rlm' will list which packages rlm is defined in.
154 This help buffer is not bogus, but instead is now relabelled
155 "*help[R](rlm in packages)*".
157 * ESS[STA]: add "//" as comment starting character to syntax-table.
159 Changes/New Features in 5.2.8:
160 * iESS: [Tab] completes *file* names "inside string" as in earlier
161 (<= 5.2.3) ESS versions.
163 Changes/New Features in 5.2.7:
164 * If you use Custom to change the variable ess-toolbar-items, the
165 new toolbar is used in all subsequent ESS buffers.
167 * ESS[SAS]: new feature: if ess-sas-log-max >0 and your .log grows
168 to more than ess-sas-log-max bytes, just the first ess-sas-log-max
169 bytes are refreshed; this is helpful when your .sas program
170 generates lots of error messages and gets too big for emacs to
173 * ESS[R/S]: `M-;' in R/S editing modes will now indent with either
174 one or two hashes depending on context.
176 * ESS[R]: David Whiting's Sweave extensions (to 'noweb') are now
177 available (from ess-swv.el loaded by default).
179 Changes/New Features in 5.2.6:
180 * Removed non-ASCII characters in a few files.
182 * ESS[R]: now works better when UTF-8 locale is active; in
183 particular, you get correct directional quotes in R's startup
184 message for R-devel (unstable development version of R 2.1.0)
185 when using environment variables LANGUAGE=en@quot
188 * ESS[SAS]: toggling of .log mode improved (`F10'); toggling of .lst
189 mode now also available (`C-F10'); killing all buffers associated
190 with .sas program no longer bound to `C-F10' since its a bit
193 * S-Plus 7 for Windows is now recognized.
195 * ESS[S] (incl. R): in auto-fill mode, strings are not wrapped
198 * ESS[S] (incl. R): font-lock now correctly differs between R and S,
199 e.g., for "_"; both now fontify warning(.) and S does terminate()
202 * Support for `bell' aka `beep' aka `ding' aka `alarm' in all
203 inferior modes: When \a is output "to the the console" at the
204 beginning of a line, the bell is rung.
206 Changes/New Features in 5.2.5:
207 * ESS[R]: `C-c C-q' or `Quit S' from the menu now should work (again
208 and less klunkily) and do not append `-exited' to the buffer name.
209 Further, the behavior of `(ess-cleanup)', called from ess-quit,
210 now depends on the new customizable variable
211 `ess-S-quit-kill-buffers-p' which defaults to `nil'.
212 Consequently, the question _"Delete all buffers associated with
213 ..?"_ will not be asked anymore by default.
215 * ESS[SAS] - ess-ebcdic-to-ascii-search-and-replace will now work
216 with the `recode' application as well which is available on many
219 * ESS[S] (incl. R): Name completion for slots of S4 objects now
222 Changes/New Features in 5.2.4:
223 * The documentation now includes an overview of how to use the emacs
224 TAGS facility for S functions. (The distribution also used to
225 contain a directory `etc/other/Tags' where a ~1990 version of
226 `etags.c' was distributed; this is no longer relevant and so has
229 * ESS[SAS] - When you are working with EBCDIC files on an ASCII
230 platform, .log NOTEs may display as gibberish since the EBCDIC
231 characters are not converted to ASCII prior to their display. So,
232 the function ess-ebcdic-to-ascii-search-and-replace is provided for
233 convenience and is bound to `C-F11'. This function requires the
234 `dd' command (only available on unix or unix-like platforms).
236 * ESS: Completion of object names is now always done dynamically
237 rather than allowing the option of using a pre-computed database
238 (by `ess-create-object-name-db') since modern computers seem fast
239 enough for dynamic completion. (We expect few users, if any, have
240 been using the pre-computed database method.)
242 * ESS: object completion in iESS buffers running on Windows was very
243 slow (for GNU Emacs, but not XEmacs) and has now been fixed.
244 Further, it was more or less broken for all versions of S-plus 6.x,
245 and has been fixed to work everywhere but with the Windows' GUI of
246 S-plus. The list of objects now shows unique names also when an
247 object appears more than once in the search path.
249 * ESS[R]: Completion of object names now also includes those
252 Changes/New Features in 5.2.3:
253 * ESS: When new inferior ESS processes are created, by default they
254 will replace the current buffer (this restores behavior from pre
255 5.2.0). If you wish new ESS processes to start in another window
256 of the current frame, set inferior-ess-same-window to nil.
258 * New variables inferior-Splus-args and inferior-R-args provide a
259 way to pass command line arguments to starting S and R processes.
261 Changes/New Features in 5.2.2:
262 * bug-fixes for 5.2.1 (require 'executable), html docs, etc.
264 * ess-lisp-directory/../doc/info added to Info-directory-list if
265 ess-info not found by info
267 * ESS[R]: If you have other versions of R on your exec-path, such as
268 "R-1.8.1" with Unix or "rw1081" with Windows, ESS will find them
269 and create appropriate functions, such as `M-x R-1.8.1' or `M-x
270 rw1081', for calling them. By default only Unix programs
271 beginning "R-1" and "R-2" and Windows programs parallel to the
272 version of R in your exec-path will be found, but see
273 ess-r-versions and ess-rterm-versions for ways to find other
276 * ESS[R]: Other versions of R, such as "R-1.8.1" on Unix and
277 "rw1081" on Windows, are added to the "ESS / Start Process /
280 * ESS[S]: If you have other versions of S-Plus on your Windows
281 computer, such as S-Plus 6.1 or S-Plus 4.5, ESS will find them and
282 create appropriate functions, such as `M-x splus61', for calling
283 the console version (Sqpe) inside an emacs buffer. By default only
284 programs installed in the default location will be found, but see
285 ess-SHOME-versions for ways to find other versions of S-Plus.
287 * ESS[S]: Other versions of Sqpe on Windows, such as "splus61", are
288 added to the "ESS / Start Process / Other" menu.
290 * ESS[R]: (bug fix) ess-quit (bound to `C-c C-q') should now quit the
291 inferior R process, when issued from either the inferior buffer,
294 Changes/New Features in 5.2.1:
295 * ESS[S] (R and S-plus): now have toolbar support with icons to
296 evaluate code in the inferior process or to switch there. This
297 code is experimental and likely to change as XEmacs/Emacs issues
298 get resolved. The toolbar should be enabled if your Emacs displays
299 images, but can be disabled with the variable ess-use-toolbar.
300 Thanks to David Smith from Insightful for the S-plus logo.
302 * ESS[SAS]: ess-sas-graph-view (`F12') enhanced; you can specify
303 external file viewers for each graphics file type via the alist
304 ess-sas-graph-view-viewer-alist; also .jpg/.gif are now handled by
305 image-mode on XEmacs, if available, otherwise by graphics
308 Changes/New Features in 5.2.0:
309 * ESS[BUGS]: new info documentation! now supports interactive
310 processing thanks to Aki Vehtari (mailto:Aki.Vehtari@hut.fi); new
311 architecture-independent unix support as well as support for BUGS
314 * ESS[SAS]: convert .log to .sas with ess-sas-transcript; info
315 documentation improved; Local Variable bug fixes; SAS/IML
316 statements/functions now highlighted; files edited remotely by
317 ange-ftp/EFS/tramp are recognized and pressing SUBMIT opens a
318 buffer on the remote host via the local variable
319 ess-sas-shell-buffer-remote-init which defaults to "ssh"; changed
320 the definition of the variable ess-sas-edit-keys-toggle to boolean
321 rather than 0/1; added the function ess-electric-run-semicolon
322 which automatically reverse indents lines containing only "run;";
323 `C-F1' creates MS RTF portrait from the current buffer; `C-F2'
324 creates MS RTF landscape from the current buffer; `C-F9' opens a
325 SAS DATASET with PROC INSIGHT rather than PROC FSVIEW; "inferior"
326 aliases for SAS batch: `C-c C-r' for submit region, `C-c C-b' for
327 submit buffer, `C-c C-x' for goto .log; `C-c C-y' for goto .lst
329 * ESS[S]: Pressing underscore ("_") once inserts " <- " (as before);
330 pressing underscore twice inserts a literal underscore. To stop
331 this smart behaviour, add "(ess-toggle-underscore nil)" to your
332 .emacs after ess-site has been loaded;
333 ess-dump-filename-template-proto (new name!) now can be customized
334 successfully (for S language dialects); Support for Imenu has been
335 improved; set ess-imenu-use-S to non-nil to get an "Imenu-S" item
336 on your menubar; ess-help: Now using nice underlines (instead of
339 * ESS[R]: After (require 'essa-r), `M-x ess-r-var' allows to load
340 numbers from any Emacs buffer into an existing *R* process; `M-x
341 ess-rdired' gives a "directory editor" of R objects; fixed
342 ess-retr-lastvalue-command, i.e. .Last.value bug (thanks to David
345 * ESS: Support for creating new window frames has been added to ESS.
346 Inferior ESS processes can be created in dedicated frames by
347 setting inferior-ess-own-frame to t. ESS help buffers can also
348 open in new frames; see the documentation for ess-help-own-frame
349 for details. (Thanks to Kevin Rodgers for contributing code.)
351 Changes/New Features in 5.1.24:
352 * The version number is now correct even inside ESS/Emacs
354 Changes/New Features in 5.1.23:
355 * Minor more Makefile clean up.
357 Changes/New Features in 5.1.22:
358 * Besides info documentation, PDF and HTML documentation are also
359 provided (instead of built using "make") and available on the web
360 as well; see ESS web page (http://ess.r-project.org/) and StatLib
361 (http://lib.stat.cmu.edu/general/ESS/doc)
363 * Now that info documentation is available, the README.* files are
364 no longer supported. However, they are still distributed for what
367 * ESS is now an XEmacs package! See XEmacs Installation HOWTO
368 (http://www.xemacs.org/Install/index.html) for details
369 (specifically, items 10-15).
371 * ESS[SAS]: more user-friendly enhancements for remote SAS batch
372 jobs with Kermit file transfers (LOG and OUTPUT function key
373 features now supported). Multiple shells now supported so you can
374 run SAS on different computers from different buffers by setting
375 the buffer-local variable ess-sas-shell-buffer to unique buffer
378 * Major re-vamping of Makefile/Makeconf.
380 Changes/New Features in 5.1.21:
381 * ESS[SAS]: info documentation now available!, see ESS->Help for
382 SAS; `F12' opens GSASFILE nearest point for viewing either within
383 emacs, when available, or via an external viewer; more syntax
384 highlighting keywords; more enhancements for remote SAS batch jobs
385 with Kermit; new framework for remote SAS interactive jobs, see
388 * ESS[S]: info documentation now available!, see ESS->Help for the S
391 * Makefile: tag now independent of rel; info files made by
392 doc/Makefile and installed in new info sub-directory
394 Changes/New Features in 5.1.20:
395 * New `options()$STERM' in the S dialects (S, S-Plus, R). The S
396 program can determine the environment in which it is currently
397 running. ESS sets the option to `iESS' or `ddeESS' when it starts
398 an S language process. We recommend other specific values for S
399 language processes that ESS does not start.
401 * New `ess-mouse-me' function, assigned to S-mouse-3 by default.
402 User may click on a word or region and then choose from the menu
403 to display the item, or a summary, or a plot, etc. This feature
404 is still under development.
406 * GNU Emacs 21.1 is now supported (fixed for S dialects, SAS & BUGS),
407 (some from Stephen Eglen).
409 * XEmacs 21.x is now supported (fixed w32-using-nt bug)
411 * XEmacs on Win (NT) is better supported.
413 * Workaround for bug in Sqpe+6 (S-PLUS 6 for Win).
415 * should now work even when imenu is not available (for old
418 * ESS[SAS]: XEmacs-Imenu fix; `C-TAB' is globalized along with your
419 function-key definitions, if specified; you can specify your SAS
420 library definitions outside of autoexec.sas for ess-sas-data-view
421 with SAS code placed in the variable ess-sas-data-view-libname,
422 also the dataset name is defaulted to the nearest permanent dataset
423 to point; Speedbar support now works for permanent datasets, please
424 ignore first./last.; new font-locking is now the default with more
425 improvements for font-locking PROCs, macro statements, * ; and %* ;
426 comments; you can toggle sas-log-mode with `F10' which will
427 font-lock your .log (if it isn't too big); submit remote .sas
428 files accessed with ange-ftp, EFS or Tramp (Kermit is
429 experimental) by setting ess-sas-submit-method to 'sh;
430 ess-sas-submit-command and ess-sas-submit-command-options are
431 buffer-local so you can have local file variable sections at the
432 end of your .sas files to request different executables or specify
433 special options and the local file variables are re-read at submit
434 instead of only at file open so that if you make a change it is
435 picked up immediately;
437 * ESS[BUGS]: font-lock with `in' fixed.
439 * for STATA: font-lock bug fixed.
441 * for Rd mode: `C-c C-v' and `switch-process' in menu. further,
442 `C-c C-f' prefix (Rd-font) for inserting or surrounding a word by
443 things such as \code{.}, \code{\link{.}}, \emph{.} etc.
445 * new functions (ess-directory-function) and (ess-narrow-to-defun)
446 ess-directory <-> default-directory logic (Jeff Mincy).
448 * Re-organized Makefile and fixed a few bugs.
450 Changes/New Features in 5.1.19:
451 * S+6 now supported (Tony Rossini (Unix) and Rich Heiberger
454 * New BUGS support through ESS[BUGS] mode (Rodney Sparapani)
455 Templates assist you in writing .bug and .cmd code (.cmd and .log
456 are replaced by .bmd and .bog to avoid emacs extension collisions).
457 Substitution" parameters facilitate "automagic" generation of
458 data...in" and "init...in" filenames, "const N=" from your data
459 file and "monitor()/stats()" commands. Activated by pressing
462 * Fixes for `ess-smart-underscore' SAS breakage (Rich Heiberger)
464 * You can change between PC and Unix, local and global SAS
465 function-key definitions interactively (Rich Heiberger)
467 * `C-Submit' a highlighted region to SAS batch (Rodney Sparapani)
469 * New and improved SAS syntax highlighting (Rodney Sparapani) To get
470 the new functionality, set ess-sas-run-make-regexp to nil. Also
471 available in .log files via `F10'.
473 * Open a permanent SAS dataset for viewing via `F9' (Rodney
474 Sparapani) You must have the library defined in autoexec.sas for
477 * User-friendly defaults for `sas-program',
478 `ess-sas-batch-pre-command' and `ess-sas-batch-post-command' as
479 well Customize support for these and other ESS[SAS] variables
482 * `ess-sas-suffix-2' now defaults to .dat via `F11' (Rodney
485 * Emacs/XEmacs, Unix/Windows issues collectively handled in
488 * defadvice solves problem of missing *ESS* (thanks to Jeff Mincy)
490 * Improved manual a bit by including things that were only in
493 Changes/New Features in 5.1.18:
494 * New `ess-smart-underscore' function, now assigned to "_" by
495 default. Inserts `ess-S-assign' (customizable " <- "), unless
496 inside string and comments where plain "_" is used instead. (MM)
498 * Fixes for longstanding interactive SAS breakage (RMH)
500 Changes/New Features in 5.1.17:
501 * Documentation for Windows Installation (Rich Heiberger)
503 * removal of ess-vars, finalization of customize support (in the
504 sense that there is no more use of ess-vars, but that we need to
505 fix ess-cust) (AJ Rossini)
507 * Many small (and large) fixes/contributions (MMaechler)
509 * addition of the "S-equal" variable and provide `M-x
510 ess-add-MM-keys' a way to remap "_" to `ess-S-assign', typically "
511 <- ", but customizable. (MMaechler)
513 Changes/New Features in 5.1.16:
518 Changes/New Features in 5.1.15:
521 Changes/New Features in 5.1.14:
522 * Yet more fixes to SAS mode, (Rich Heiberger and Rodney Sparapani)
524 * Customize support (for most Emacsen which support it) (AJRossini)
526 * ARC and ViSta support out of the box, and fixes for XLispStat
529 Changes/New Features in 5.1.13:
530 * Version numbering finally all depending on the ./VERSION file,
531 thanks to Martin Maechler.
533 * Yet more fixes to SAS mode, thanks to Rich Heiberger.
535 Changes/New Features in 5.1.12:
536 * Splus 5.1 stabilized, thanks to Martin Maechler, Bill Venables,
537 Chuck Taylor, and others.
539 * More fixes to SAS mode, thanks to Rodney Sparapani and Rich
542 Changes/New Features in 5.1.11:
543 * More fixes to Stata mode, thanks to Brendan Halpin
544 (mailto:brendan@essex.ac.uk).
546 * fixed bugs in ESS-elsewhere, thanks to many testers
548 * README.SPLUS4WIN has DETAILED instructions for S-PLUS 2000, thanks
549 to David Brahm (mailto:brahm@alum.mit.edu).
551 * Fixes to SAS mode, thanks to Rodney Sparapani
553 Changes/New Features in 5.1.10:
554 * More fixes to Stata mode
556 * primitive generic version of ESS-elsewhere
558 * Small fixes to SAS/Stata.
560 Changes/New Features in 5.1.9:
563 * Literate Data Analysis using Noweb works
565 Changes/New Features in 5.1.8:
568 * R documentation mode defaults changed
570 Changes/New Features in 5.1.2:
571 * able to use inferior iESS mode to communicate directly with a
572 running S-Plus 4.x process using the Microsoft DDE protocol. We
573 use the familiar (from Unix ESS) `C-c C-n' and related key
574 sequences to send lines from the S-mode file to the inferior S
575 process. We continue to edit S input files in ESS[S] mode and
576 transcripts of previous S sessions in ESS Transcript mode. All

686 1.7 Getting the Latest Version
687 ==============================
689 The latest released version of ESS is always available on the web at:
690 ESS web page (http://ess.r-project.org) or StatLib
691 (http://lib.stat.cmu.edu/general/ESS/)
693 The latest development version of ESS is available via
694 `https://svn.R-project.org/ESS/', the ESS Subversion repository. If
695 you have a Subversion client (see `http://subversion.tigris.org/'), you
696 can download the sources using:
697 % svn checkout https://svn.r-project.org/ESS/trunk PATH
698 which will put the ESS files into directory PATH. Later, within
699 that directory, `svn update' will bring that directory up to date.
700 Windows-based tools such as TortoiseSVN are also available for
701 downloading the files. Alternatively, you can browse the sources with a
702 web browser at: ESS SVN site (https://svn.r-project.org/ESS/trunk).
703 However, please use a subversion client instead to minimize the load
706 If you remove other versions of ESS from your emacs load-path, you
707 can then use the development version by adding the following to .emacs:
709 (load "/path/to/ess-svn/lisp/ess-site.el")
711 Note that https is required, and that the SSL certificate for the
712 Subversion server of the R project is
714 Certificate information:
715 - Hostname: svn.r-project.org
716 - Valid: from Jul 16 08:10:01 2004 GMT until Jul 14 08:10:01 2014 GMT
717 - Issuer: Department of Mathematics, ETH Zurich, Zurich, Switzerland, CH
718 - Fingerprint: c9:5d:eb:f9:f2:56:d1:04:ba:44:61:f8:64:6b:d9:33:3f:93:6e:ad
720 (currently, there is no "trusted certificate"). You can accept this
721 certificate permanently and will not be asked about it anymore.
723 1.8 Installation (from tar file)
724 ================================
726 We now discuss installation, which might happen under Unix or Microsoft
727 Windows. First, we discuss Unix installation. *Note Unix
730 For Microsoft Windows Installation please skip to the *Note
731 Microsoft Windows installation::.
733 1.9 Unix installation
734 =====================
736 1. `cd' to a directory where you want to install ESS, creating it if
737 necessary. This directory will be referred to below as `ESSDIR'.
739 2. Retrieve the latest version from ESS downloads area
740 (http://ess.r-project.org/downloads/ess) to `ESSDIR'.
742 3. Decompress/unarchive the files from the disribution.
743 Either, `gunzip < ess-VERSION.tar.gz | tar xf -',
744 or using GNU tar, `tar zxf ess-VERSION.tar.gz'.
746 The `tar' command will create the subdirectory `ess-VERSION' and
747 install the files there.
749 4. Edit the file `ESSDIR/ess-VERSION/lisp/ess-site.el' as explained
750 in the comments section of that file.
753 (load "ESSDIR/ess-VERSION/lisp/ess-site")
754 to your user or system installation file (GNU Emacs uses
755 `$HOME/.emacs' and XEmacs uses `$HOME/.xemacs/init.el' for the
756 user initialization file. GNU Emacs uses `default.el' or
757 `site-init.el' and XEmacs uses `site-start.el' for the system
760 Alternatively, if `ess-site.el' is in your current `load-path',
763 to configure emacs for ESS.
765 6. That's it! If you are installing just a local copy of ESS for
766 yourself, ESS is now ready to be used. (The remaining step below
767 is for advanced installation.) To edit statistical programs, load
768 the files with the requiste extensions (`.sas' for SAS, `.S' for
769 S-PLUS, `.R' for R, and `.lsp' for XLispStat). To start a
770 statistical process within emacs, such as R, type `M-x R'.
772 7. (OPTIONAL) READ THIS ITEM THOROUGHLY BEFORE STARTING:
774 If you want to place the compiled files in other locations edit the
775 `LISPDIR', `INFODIR' and `ETCDIR' entries in Section 1 of
776 `Makeconf' in the `ESSDIR/ess-VERSION' directory (if you are using
777 XEmacs, then see the XEmacs subsection in Section 1 of `Makeconf').
779 You can compile those files by:
782 When that completes successfully, install the compiled files:
785 _Note:_ ESS is no longer available as an XEmacs package. However,
786 ESS will work best if the XEmacs sumo tarball (all XEmacs packages
787 combined) has been installed. For more information on installing
788 XEmacs packages, see Quickstart Package Guide
789 (http://www.xemacs.org/Documentation/packageGuide.html).
792 1.10 Microsoft Windows installation
793 ===================================
795 For Microsoft Windows installation, please follow the next steps: (see
796 separate instructions above for UNIX *Note Unix installation::.
798 1. `cd' to a directory where you keep emacs lisp files, or create a
799 new directory (for example, `c:\emacs\') to hold the distribution.
800 This directory will be referred to below as "the ESS distribution
803 2. Retrieve the latest zip file (`ess-VERSION.zip') from ESS
804 downloads area (http://ess.r-project.org/downloads/ess) and store
805 it in the ESS distribution directory. Be aware that http browsers
806 on Windows frequently change the "." and "-" characters in
807 filenames to other punctuation. Please change the names back to
810 3. Extract all the files from `ess-VERSION.zip' into the ESS
811 distribution directory. In Windows Explorer, you can unpack the
812 archive by double clicking on the folder; you should then see a
813 new folder called `ess-VERSION'. Drag that folder into your ESS
814 distribution directory.
817 (load "C:/emacs/ess-VERSION/lisp/ess-site")
818 to your emacs initialization file. (GNU Emacs uses the filename
819 `~/.emacs' and XEmacs uses the filename `~/.xemacs/init.el' for
820 the initialization file. The tilde is recognised by emacs as your
821 HOME directory, i.e. the value of your HOME environment variable.)
822 Replace `VERSION' above with the version number of ESS. Remember
823 to use forwardslashes `/' rather than `\\' in your filename.
825 After saving your initialization file, ESS is now installed.
826 Start a new emacs and you should be ready to use ESS. For
827 example, to edit statistical programs, load the files with the
828 requisite extensions (".sas" for SAS, ".S" or "s" or "q" or "Q"
829 for S-PLUS, ".r" or ".R" for R, and ".lsp" for XLispStat). One
830 further step is needed if you wish to run statistical processes,
833 5. To run statistical processes under ESS, Windows users will need to
834 make sure that the directories for the software they will be using
835 is in the PATH environment variable. On Windows 9x, add lines
836 similar to the following to your `c:\autoexec.bat' file:
837 path=%PATH%;c:\progra~1\insightful\splus70\cmd
838 On Windows NT/2000/XP, add the directories to the PATH using the
839 `My Computer/Control Panel/System/Advanced/Environment Variables'
840 menu. Note that the directory containing the program is added to
841 the PATH, not the program itself. One such line is needed for
842 each software program. Be sure to use the abbreviation `progra~1'
843 and not the long version with embedded blanks. Use backslashes
846 An alternative, for R users, is that rather than adjusting the PATH
847 variable, you can add the following to your emacs initialization
848 file (and restart emacs):
849 (setq inferior-R-program-name "C:/progra~1/R/R-2.2.1/bin/Rterm.exe")
850 This assumes that you have installed R-2.2.1 in the default
851 location. Change the path otherwise to point to other locations.
853 To start the S-PLUS [67].x GUI from ESS under emacs:
854 1. If you use Cygwin bash as your primary shell, then
858 2. If you use the MSDOS prompt window as your primary shell, then
860 You will then be asked for a pathname ("S starting data
861 directory?"), from which to start the process. The prompt will
862 propose your current directory as the default. ESS will start the
863 S-PLUS GUI. There will be slight delay during which emacs is
864 temporarily frozen. ESS will arrange for communication with the
865 S-PLUS GUI using the DDE protocol. Send lines or regions from the
866 emacs buffer containing your S program (for example, `myfile.s')
867 to the S-PLUS Commands Window with the `C-c C-n' or `C-c C-r' keys.
868 (If you are still using S-PLUS 4.x or 2000,\ then use `M-x S+4' or
871 To start an S-PLUS [67].x session inside an emacs buffer--and
872 without the S-PLUS GUI:
875 This works with both the bash and msdos shells. You will then be
876 asked for a pathname ("S starting data directory?"), from which to
877 start the process. The prompt will propose your current directory
878 as the default. You get Unix-like behavior, in particular the
879 entire transcript is available for emacs-style search commands.
880 Send lines or regions from the emacs buffer containing your S
881 program (for example, `myfile.s') to the *S+6* buffer with the
882 `C-c C-n' or `C-c C-r' keys. Interactive graphics are available
883 with Sqpe by using the java library supplied with S-PLUS 6.1 and
884 newer releases. Enter the commands:
887 Graphs can be saved from the `java.graph' device in several
888 formats, but not PostScript. If you need a PostScript file you
889 will need to open a separate `postscript' device. (If you are
890 still using S-PLUS 4.x or 2000, then use `M-x Sqpe+4'.)
892 To connect to an already running S-PLUS GUI (started, for example,
893 from the S-PLUS icon):
896 M-x S+6-msdos-existing
897 You will then be asked for a pathname ("S starting data
898 directory?"), from which to start the process. The prompt will
899 propose your current directory as the default. ESS will arrange
900 for communication with the already running S-PLUS GUI using the
901 DDE protocol. Send lines or regions from the emacs buffer
902 containing your S program (for example, `myfile.s') to the S-PLUS
903 Commands Window with the `C-c C-n' or `C-c C-r' keys. (If you are
904 still using S-PLUS 4.x or 2000, then use `M-x S+4-existing' or
905 `M-x S+4-msdos-existing'.)
907 If you wish to run R, you can start it with:
910 XLispStat can not currently be run with
912 Hopefully, this will change. However, you can still edit with
913 emacs, and cut and paste the results into the XLispStat *Listener*
914 Window under Microsoft Windows.
922 Please send bug reports, suggestions etc. to
923 <ESS-bugs@stat.math.ethz.ch>
925 The easiest way to do this is within Emacs by typing
927 `M-x ess-submit-bug-report'
929 This also gives the maintainers valuable information about your
930 installation which may help us to identify or even fix the bug.
932 If Emacs reports an error, backtraces can help us debug the problem.
933 Type "M-x set-variable RET debug-on-error RET t RET". Then run the
934 command that causes the error and you should see a *Backtrace* buffer
935 containing debug information; send us that buffer.
937 Note that comments, suggestions, words of praise and large cash
938 donations are also more than welcome.
943 There is a mailing list for discussions and announcements relating to
944 ESS. Join the list by sending an e-mail with "subscribe ess-help" (or
945 "help") in the body to <ess-help-request@stat.math.ethz.ch>;
946 contributions to the list may be mailed to
