4 The ESS Developers proudly announce the release of ESS
8 Emacs Speaks Statistics (ESS) provides an intelligent, consistent
9 interface between the user and the software. ESS interfaces with
10 S-PLUS, R, SAS, BUGS and other statistical analysis packages under the
11 Unix, Microsoft Windows, and Apple Mac OS operating systems. ESS is a
12 package for the GNU Emacs and XEmacs text editors whose features ESS
13 uses to streamline the creation and use of statistical software. ESS
14 knows the syntax and grammar of statistical analysis packages and
15 provides consistent display and editing features based on that
16 knowledge. ESS assists in interactive and batch execution of
17 statements written in these statistical analysis languages.
19 ESS is freely available under the GNU General Public License (GPL).
20 Please read the file COPYING which comes with the distribution, for
21 more information about the license. For more detailed information,
22 please read the README files that come with ESS.
24 1.1 Getting the Latest Version
25 ==============================
27 The latest released version of ESS is always available on the web at:
28 ESS web page (http://ess.r-project.org) or StatLib
29 (http://lib.stat.cmu.edu/general/ESS/)
31 The latest development version of ESS is available via
32 `https://svn.R-project.org/ESS/', the ESS Subversion repository. If
33 you have a Subversion client (see `http://subversion.tigris.org/'), you
34 can download the sources using:
35 % svn checkout https://svn.r-project.org/ESS/trunk PATH
36 which will put the ESS files into directory PATH. Later, within
37 that directory, `svn update' will bring that directory up to date.
38 Windows-based tools such as TortoiseSVN are also available for
39 downloading the files. Alternatively, you can browse the sources with a
40 web browser at: ESS SVN site (https://svn.r-project.org/ESS/trunk).
41 However, please use a subversion client instead to minimize the load
44 If you remove other versions of ESS from your emacs load-path, you
45 can then use the development version by adding the following to .emacs:
47 (load "/path/to/ess-svn/lisp/ess-site.el")
49 Note that https is required, and that the SSL certificate for the
50 Subversion server of the R project is
52 Certificate information:
53 - Hostname: svn.r-project.org
54 - Valid: from Jul 16 08:10:01 2004 GMT until Jul 14 08:10:01 2014 GMT

153 ---------- Footnotes ----------
155 (1) require the files.el patch to revert-buffer for the Local
156 Variables updating problem
161 Versions 5.2.x are meant to be release-quality versions. While some
162 new features are being introduced, we are cleaning up and improving the
163 interface. We know about some remaining documentation inconsistencies.
164 Patches or suggested fixes with bug reports are much appreciated!
169 There is a mailing list for discussions and announcements relating to
170 ESS. Join the list by sending an e-mail with "subscribe ess-help" (or
171 "help") in the body to <ess-help-request@stat.math.ethz.ch>;
172 contributions to the list may be mailed to
173 <ess-help@stat.math.ethz.ch>. Rest assured, this is a fairly
174 low-volume mailing list.
176 The purposes of the mailing list include
178 * helping users of ESS to get along with it.
180 * discussing aspects of using ESS on Emacs and XEmacs.
182 * suggestions for improvements.
184 * announcements of new releases of ESS.
186 * posting small patches to ESS.
191 Please send bug reports, suggestions etc. to
192 <ESS-bugs@stat.math.ethz.ch>
194 The easiest way to do this is within Emacs by typing
196 `M-x ess-submit-bug-report'
198 This also gives the maintainers valuable information about your
199 installation which may help us to identify or even fix the bug.
201 If Emacs reports an error, backtraces can help us debug the problem.
202 Type "M-x set-variable RET debug-on-error RET t RET". Then run the
203 command that causes the error and you should see a *Backtrace* buffer
204 containing debug information; send us that buffer.
206 Note that comments, suggestions, words of praise and large cash
207 donations are also more than welcome.

235 in the file COPYING in the same directory as this file for more details.
240 Changes/New Features in 5.2.13:
241 * New variable, `ess-use-inferior-program-name-in-buffer-name',
242 which uses the executable name instead of the dialect name for R.
245 * ESS[S] `ess-execute-screen-options' now also works correctly when
246 there is more than one window *side-by-side* in the same frame and
247 runs in the correct buffer also when there is more than one S
250 Changes/New Features in 5.2.12:
251 * ESS[SAS]: `M-;' fixed, but the XEmacs function `comment-dwim' may
252 be broken, if so, use `M-x comment-region' and `M-x
253 uncomment-region' instead; only valid PROCs are fontified which is
254 very helpful finding syntax errors (currently supported: BASE,
255 ETS, FSP, GRAPH, IML, INSIGHT and STAT); the "feature" where
256 `F'-keys take you to an empty buffer when the requested
257 destination is a file that does not exist has been fixed, now the
258 request results in a no-op. Further, sas-mode now also works in
261 * Rterm/Cygwin combination works under Microsoft Windows.
263 * ESS[R]: internal calls use baseenv() instead of NULL and define
264 'baseenv' where needed.
266 * New experimental support for installing ESS. See the file
267 `lisp/ess-install.el'.
269 Changes/New Features in 5.2.11:
270 * ESS Info entry and `dir' handled more effectively for GNU Emacs
273 * ESS[SAS]: temporary files created for batch submission of a region
274 are now named based on the current file; see `ess-sas-file-root'
275 for details; all `lag' and `dif' functions now fontified correctly
277 * iESS[SAS]: fixed a few nagging bugs, however, still does not
278 appear to work at this time; please let us know if you have any
281 * ESS[S]: Support for running other versions of Splus has been added
282 for unix. Two new variables, `ess-s-versions' and
283 `ess-s-versions-list', are used to tell ESS what other versions of
284 Splus you would like to run.
286 Changes/New Features in 5.2.10:
287 * ESS[R]: ess-r-versions can no longer be customized (since the
288 customization was not taking effect unless customizations were
289 loaded before ESS). Its value has been changed so that it will
290 also find R executables beginning "R-devel" and "R-patched". If
291 you wish to change this variable, it must be set in your `.emacs'
292 before ESS is loaded.
294 * Installation with GNU Make enhanced: unix and unix-like operating
295 systems will now be able to install ESS for all users in either a
296 GNU Emacs site-lisp or an XEmacs package configuration by editing
297 `lisp/ess-site.el' and `Makeconf' accordingly, then issuing `make
300 * ESS[S]: Filename completion (inside strings) now also works in
301 XEmacs for R and S-plus.
303 Changes/New Features in 5.2.9:
304 * ESS[R] for Windows: the \ directory character bug with respect to
305 ess-load-file has been eradicated.
307 * iESS[SAS]: `C-c C-r' and `C-c C-b' once again work as intended and
310 * ESS[S]: M-x ess-fix-EQ-assign is a bit more agressive.
312 * ESS[S]: Imenu now also shows setAs(), etc.
314 * ESS[R]: R function pattern enhanced with underlying code such that
315 `M-C-a' (`ess-beginning-of-function') etc now work for many more
316 cases, including S4 method definitions.
318 * iESS[R]: myOwnhelp(1) no longer wrongly triggers help(1).
320 * ESS[R]: Improved detection of bogus help buffers: valid help
321 buffers containing with the string "no documentation"(e.g. contour)
322 were being treated as bogus.
324 * ESS[R]: In R help buffers, if `options("help.try.all.packages" =
325 TRUE)' then `?rlm' will list which packages rlm is defined in.
326 This help buffer is not bogus, but instead is now relabelled
327 "*help[R](rlm in packages)*".
329 * ESS[STA]: add "//" as comment starting character to syntax-table.
331 Changes/New Features in 5.2.8:
332 * iESS: [Tab] completes *file* names "inside string" as in earlier
333 (<= 5.2.3) ESS versions.
335 Changes/New Features in 5.2.7:
336 * If you use Custom to change the variable ess-toolbar-items, the
337 new toolbar is used in all subsequent ESS buffers.
339 * ESS[SAS]: new feature: if ess-sas-log-max >0 and your .log grows
340 to more than ess-sas-log-max bytes, just the first ess-sas-log-max
341 bytes are refreshed; this is helpful when your .sas program
342 generates lots of error messages and gets too big for emacs to
345 * ESS[R/S]: `M-;' in R/S editing modes will now indent with either
346 one or two hashes depending on context.
348 * ESS[R]: David Whiting's Sweave extensions (to 'noweb') are now
349 available (from ess-swv.el loaded by default).
351 Changes/New Features in 5.2.6:
352 * Removed non-ASCII characters in a few files.
354 * ESS[R]: now works better when UTF-8 locale is active; in
355 particular, you get correct directional quotes in R's startup
356 message for R-devel (unstable development version of R 2.1.0)
357 when using environment variables LANGUAGE=en@quot
360 * ESS[SAS]: toggling of .log mode improved (`F10'); toggling of .lst
361 mode now also available (`C-F10'); killing all buffers associated
362 with .sas program no longer bound to `C-F10' since its a bit
365 * S-Plus 7 for Windows is now recognized.
367 * ESS[S] (incl. R): in auto-fill mode, strings are not wrapped
370 * ESS[S] (incl. R): font-lock now correctly differs between R and S,
371 e.g., for "_"; both now fontify warning(.) and S does terminate()
374 * Support for `bell' aka `beep' aka `ding' aka `alarm' in all
375 inferior modes: When \a is output "to the the console" at the
376 beginning of a line, the bell is rung.
378 Changes/New Features in 5.2.5:
379 * ESS[R]: `C-c C-q' or `Quit S' from the menu now should work (again
380 and less klunkily) and do not append `-exited' to the buffer name.
381 Further, the behavior of `(ess-cleanup)', called from ess-quit,
382 now depends on the new customizable variable
383 `ess-S-quit-kill-buffers-p' which defaults to `nil'.
384 Consequently, the question _"Delete all buffers associated with
385 ..?"_ will not be asked anymore by default.
387 * ESS[SAS] - ess-ebcdic-to-ascii-search-and-replace will now work
388 with the `recode' application as well which is available on many
391 * ESS[S] (incl. R): Name completion for slots of S4 objects now
394 Changes/New Features in 5.2.4:
395 * The documentation now includes an overview of how to use the emacs
396 TAGS facility for S functions. (The distribution also used to
397 contain a directory `etc/other/Tags' where a ~1990 version of
398 `etags.c' was distributed; this is no longer relevant and so has
401 * ESS[SAS] - When you are working with EBCDIC files on an ASCII
402 platform, .log NOTEs may display as gibberish since the EBCDIC
403 characters are not converted to ASCII prior to their display. So,
404 the function ess-ebcdic-to-ascii-search-and-replace is provided for
405 convenience and is bound to `C-F11'. This function requires the
406 `dd' command (only available on unix or unix-like platforms).
408 * ESS: Completion of object names is now always done dynamically
409 rather than allowing the option of using a pre-computed database
410 (by `ess-create-object-name-db') since modern computers seem fast
411 enough for dynamic completion. (We expect few users, if any, have
412 been using the pre-computed database method.)
414 * ESS: object completion in iESS buffers running on Windows was very
415 slow (for GNU Emacs, but not XEmacs) and has now been fixed.
416 Further, it was more or less broken for all versions of S-plus 6.x,
417 and has been fixed to work everywhere but with the Windows' GUI of
418 S-plus. The list of objects now shows unique names also when an
419 object appears more than once in the search path.
421 * ESS[R]: Completion of object names now also includes those
424 Changes/New Features in 5.2.3:
425 * ESS: When new inferior ESS processes are created, by default they
426 will replace the current buffer (this restores behavior from pre
427 5.2.0). If you wish new ESS processes to start in another window
428 of the current frame, set inferior-ess-same-window to nil.
430 * New variables inferior-Splus-args and inferior-R-args provide a
431 way to pass command line arguments to starting S and R processes.
433 Changes/New Features in 5.2.2:
434 * bug-fixes for 5.2.1 (require 'executable), html docs, etc.
436 * ess-lisp-directory/../doc/info added to Info-directory-list if
437 ess-info not found by info
439 * ESS[R]: If you have other versions of R on your exec-path, such as
440 "R-1.8.1" with Unix or "rw1081" with Windows, ESS will find them
441 and create appropriate functions, such as `M-x R-1.8.1' or `M-x
442 rw1081', for calling them. By default only Unix programs
443 beginning "R-1" and "R-2" and Windows programs parallel to the
444 version of R in your exec-path will be found, but see
445 ess-r-versions and ess-rterm-versions for ways to find other
448 * ESS[R]: Other versions of R, such as "R-1.8.1" on Unix and
449 "rw1081" on Windows, are added to the "ESS / Start Process /
452 * ESS[S]: If you have other versions of S-Plus on your Windows
453 computer, such as S-Plus 6.1 or S-Plus 4.5, ESS will find them and
454 create appropriate functions, such as `M-x splus61', for calling
455 the console version (Sqpe) inside an emacs buffer. By default only
456 programs installed in the default location will be found, but see
457 ess-SHOME-versions for ways to find other versions of S-Plus.
459 * ESS[S]: Other versions of Sqpe on Windows, such as "splus61", are
460 added to the "ESS / Start Process / Other" menu.
462 * ESS[R]: (bug fix) ess-quit (bound to `C-c C-q') should now quit the
463 inferior R process, when issued from either the inferior buffer,
466 Changes/New Features in 5.2.1:
467 * ESS[S] (R and S-plus): now have toolbar support with icons to
468 evaluate code in the inferior process or to switch there. This
469 code is experimental and likely to change as XEmacs/Emacs issues
470 get resolved. The toolbar should be enabled if your Emacs displays
471 images, but can be disabled with the variable ess-use-toolbar.
472 Thanks to David Smith from Insightful for the S-plus logo.
474 * ESS[SAS]: ess-sas-graph-view (`F12') enhanced; you can specify
475 external file viewers for each graphics file type via the alist
476 ess-sas-graph-view-viewer-alist; also .jpg/.gif are now handled by
477 image-mode on XEmacs, if available, otherwise by graphics
480 Changes/New Features in 5.2.0:
481 * ESS[BUGS]: new info documentation! now supports interactive
482 processing thanks to Aki Vehtari (mailto:Aki.Vehtari@hut.fi); new
483 architecture-independent unix support as well as support for BUGS
486 * ESS[SAS]: convert .log to .sas with ess-sas-transcript; info
487 documentation improved; Local Variable bug fixes; SAS/IML
488 statements/functions now highlighted; files edited remotely by
489 ange-ftp/EFS/tramp are recognized and pressing SUBMIT opens a
490 buffer on the remote host via the local variable
491 ess-sas-shell-buffer-remote-init which defaults to "ssh"; changed
492 the definition of the variable ess-sas-edit-keys-toggle to boolean
493 rather than 0/1; added the function ess-electric-run-semicolon
494 which automatically reverse indents lines containing only "run;";
495 `C-F1' creates MS RTF portrait from the current buffer; `C-F2'
496 creates MS RTF landscape from the current buffer; `C-F9' opens a
497 SAS DATASET with PROC INSIGHT rather than PROC FSVIEW; "inferior"
498 aliases for SAS batch: `C-c C-r' for submit region, `C-c C-b' for
499 submit buffer, `C-c C-x' for goto .log; `C-c C-y' for goto .lst
501 * ESS[S]: Pressing underscore ("_") once inserts " <- " (as before);
502 pressing underscore twice inserts a literal underscore. To stop
503 this smart behaviour, add "(ess-toggle-underscore nil)" to your
504 .emacs after ess-site has been loaded;
505 ess-dump-filename-template-proto (new name!) now can be customized
506 successfully (for S language dialects); Support for Imenu has been
507 improved; set ess-imenu-use-S to non-nil to get an "Imenu-S" item
508 on your menubar; ess-help: Now using nice underlines (instead of
511 * ESS[R]: After (require 'essa-r), `M-x ess-r-var' allows to load
512 numbers from any Emacs buffer into an existing *R* process; `M-x
513 ess-rdired' gives a "directory editor" of R objects; fixed
514 ess-retr-lastvalue-command, i.e. .Last.value bug (thanks to David
517 * ESS: Support for creating new window frames has been added to ESS.
518 Inferior ESS processes can be created in dedicated frames by
519 setting inferior-ess-own-frame to t. ESS help buffers can also
520 open in new frames; see the documentation for ess-help-own-frame
521 for details. (Thanks to Kevin Rodgers for contributing code.)
523 Changes/New Features in 5.1.24:
524 * The version number is now correct even inside ESS/Emacs
526 Changes/New Features in 5.1.23:
527 * Minor more Makefile clean up.
529 Changes/New Features in 5.1.22:
530 * Besides info documentation, PDF and HTML documentation are also
531 provided (instead of built using "make") and available on the web
532 as well; see ESS web page (http://ess.r-project.org/) and StatLib
533 (http://lib.stat.cmu.edu/general/ESS/doc)
535 * Now that info documentation is available, the README.* files are
536 no longer supported. However, they are still distributed for what
539 * ESS is now an XEmacs package! See XEmacs Installation HOWTO
540 (http://www.xemacs.org/Install/index.html) for details
541 (specifically, items 10-15).
543 * ESS[SAS]: more user-friendly enhancements for remote SAS batch
544 jobs with Kermit file transfers (LOG and OUTPUT function key
545 features now supported). Multiple shells now supported so you can
546 run SAS on different computers from different buffers by setting
547 the buffer-local variable ess-sas-shell-buffer to unique buffer
550 * Major re-vamping of Makefile/Makeconf.
552 Changes/New Features in 5.1.21:
553 * ESS[SAS]: info documentation now available!, see ESS->Help for
554 SAS; `F12' opens GSASFILE nearest point for viewing either within
555 emacs, when available, or via an external viewer; more syntax
556 highlighting keywords; more enhancements for remote SAS batch jobs
557 with Kermit; new framework for remote SAS interactive jobs, see
560 * ESS[S]: info documentation now available!, see ESS->Help for the S
563 * Makefile: tag now independent of rel; info files made by
564 doc/Makefile and installed in new info sub-directory
566 Changes/New Features in 5.1.20:
567 * New `options()$STERM' in the S dialects (S, S-Plus, R). The S
568 program can determine the environment in which it is currently
569 running. ESS sets the option to `iESS' or `ddeESS' when it starts
570 an S language process. We recommend other specific values for S
571 language processes that ESS does not start.
573 * New `ess-mouse-me' function, assigned to S-mouse-3 by default.
574 User may click on a word or region and then choose from the menu
575 to display the item, or a summary, or a plot, etc. This feature
576 is still under development.
578 * GNU Emacs 21.1 is now supported (fixed for S dialects, SAS & BUGS),
579 (some from Stephen Eglen).
581 * XEmacs 21.x is now supported (fixed w32-using-nt bug)
583 * XEmacs on Win (NT) is better supported.
585 * Workaround for bug in Sqpe+6 (S-PLUS 6 for Win).
587 * should now work even when imenu is not available (for old
590 * ESS[SAS]: XEmacs-Imenu fix; `C-TAB' is globalized along with your
591 function-key definitions, if specified; you can specify your SAS
592 library definitions outside of autoexec.sas for ess-sas-data-view
593 with SAS code placed in the variable ess-sas-data-view-libname,
594 also the dataset name is defaulted to the nearest permanent dataset
595 to point; Speedbar support now works for permanent datasets, please
596 ignore first./last.; new font-locking is now the default with more
597 improvements for font-locking PROCs, macro statements, * ; and %* ;
598 comments; you can toggle sas-log-mode with `F10' which will
599 font-lock your .log (if it isn't too big); submit remote .sas
600 files accessed with ange-ftp, EFS or Tramp (Kermit is
601 experimental) by setting ess-sas-submit-method to 'sh;
602 ess-sas-submit-command and ess-sas-submit-command-options are
603 buffer-local so you can have local file variable sections at the
604 end of your .sas files to request different executables or specify
605 special options and the local file variables are re-read at submit
606 instead of only at file open so that if you make a change it is
607 picked up immediately;
609 * ESS[BUGS]: font-lock with `in' fixed.
611 * for STATA: font-lock bug fixed.
613 * for Rd mode: `C-c C-v' and `switch-process' in menu. further,
614 `C-c C-f' prefix (Rd-font) for inserting or surrounding a word by
615 things such as \code{.}, \code{\link{.}}, \emph{.} etc.
617 * new functions (ess-directory-function) and (ess-narrow-to-defun)
618 ess-directory <-> default-directory logic (Jeff Mincy).
620 * Re-organized Makefile and fixed a few bugs.
