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

154 ---------- Footnotes ----------
156 (1) require the files.el patch to revert-buffer for the Local
157 Variables updating problem
162 Versions 5.3.x are meant to be release-quality versions. While some
163 new features are being introduced, we are cleaning up and improving the
164 interface. We know about some remaining documentation inconsistencies.
165 Patches or suggested fixes with bug reports are much appreciated!
170 There is a mailing list for discussions and announcements relating to
171 ESS. Join the list by sending an e-mail with "subscribe ess-help" (or
172 "help") in the body to <ess-help-request@stat.math.ethz.ch>;
173 contributions to the list may be mailed to
174 <ess-help@stat.math.ethz.ch>. Rest assured, this is a fairly
175 low-volume mailing list.
177 The purposes of the mailing list include
179 * helping users of ESS to get along with it.
181 * discussing aspects of using ESS on Emacs and XEmacs.
183 * suggestions for improvements.
185 * announcements of new releases of ESS.
187 * posting small patches to ESS.
192 Please send bug reports, suggestions etc. to
193 <ESS-bugs@stat.math.ethz.ch>
195 The easiest way to do this is within Emacs by typing
197 `M-x ess-submit-bug-report'
199 This also gives the maintainers valuable information about your
200 installation which may help us to identify or even fix the bug.
202 If Emacs reports an error, backtraces can help us debug the problem.
203 Type "M-x set-variable RET debug-on-error RET t RET". Then run the
204 command that causes the error and you should see a *Backtrace* buffer
205 containing debug information; send us that buffer.
207 Note that comments, suggestions, words of praise and large cash
208 donations are also more than welcome.

241 Changes/New Features in 5.3.5:
242 * ESS[R] add Sven Hartenstein's "R tooltip" functionality, via new
243 file `lisp/essd-r-args.el'.
245 * ESS: functions `ess-get-pdf-viewer' and *-ps-viewer; built on new
246 customizable variables ESS-PDF-VIEWER-PREF and
247 ESS-PS-VIEWER-PREF; currently used in `ess-swv-PDF' and `*-PS'.
249 Changes/New Features in 5.3.4:
250 * ESS[R] now better work with options(error=recover); and the new
251 default of CHM help files on windows.
253 * ESS[R] some more cleanup in the "sweave" functions
255 * miscellaneous fixes
257 Changes/New Features in 5.3.3:
258 * ESS[S] fix buglet (5.3.2 only) which left command prompt in
259 "execute buffer" and hence help files.
261 * new customizable variable `ess-display-buffer-reuse-frames' set to
262 true (which changes default behavior) such that execution or help
265 Changes/New Features in 5.3.2:
266 * Classic BUGS now supported by `(require 'essd-bugs)' with ESS[BUGS]
267 and JAGS by `(require 'essd-jags)' with ESS[JAGS]. But,
268 only one of them can be used at a time since they don't play
269 nice together. Also, `C-c C-c' is now bound to the function
270 `ess-bugs-next-action' (`F12' has been retired). And
271 finally, note that `essl-bug.el' is deprecated and the
272 replacement is `essl-bugs.el'.
274 * ESS[R] Improved some of the "Sweave-make" functions (yet scarcely
275 documented) in `ess-swv.el'.
277 * ESS[S] No longer mess with .Last.value (nor in other "languages").
279 Changes/New Features in 5.3.1:
280 * See the docs for 2 ways to install ESS for XEmacs
281 1. by uncommenting the XEmacs part of Section 1 of
282 `Makeconf' and performing `make install'
284 2. by unpacking either `ess-5.3.1.tgz' or
286 `PREFIX/lib/xemacs/site-packages' on unix or
287 `PREFIX\XEmacs\site-packages' on windows
289 * ESS[R]: fixed bugs so that Rterm.exe can be found by XEmacs
291 * ESS[S]: `ess-toggle-S-assign-key' is slightly changed; in
292 particular, the default `ess-assign-key' is now `C-x ='.
294 * ESS[R]: `M-x R-site-search' is a new (slightly experimental)
295 utility similar to R's `RSiteSearch(..)' but with the advantage of
296 using Emacs' preferred browser, see `browse-url-browser-function'
298 Changes/New Features in 5.3.0:
299 * ESS[BUGS]: sanely re-format statistical output, `.bog', from
300 scientific notation to numbers rounded with 4 decimal places with
301 `M-x ess-bugs-sci-round-to-4-dp'.
303 * The keys for navigating among section headings in help buffers
304 worked, but only for one language per session; they should now
305 work for multiple languages. (They were also broken on Windows
308 * ESS[S] long standing buglets in the internal logic for loading
309 lisp code on Windows. Particularly fixed behavior in help mode
312 * New variable, `ess-use-inferior-program-name-in-buffer-name',
313 which enables using the executable name instead of the dialect
314 name for R. Feature request.
316 * ESS[S] `ess-execute-screen-options' now also works correctly when
317 there is more than one window *side-by-side* in the same frame and
318 runs in the correct buffer also when there is more than one S
321 * iESS[S] new functions `ess-eval-paragraph-and-step' and
322 `ess-eval-function-or-paragraph-and-step' are bound to keys `C-c
323 C-p' and `C-c C-c' respectively and to the menu in ESS-mode; also
324 bound in the help mode (for evaluating examples).
326 * ESS[S] new function `ess-toggle-S-assign-key' allows to assign the
327 " <- " insertion to an arbitrary key.
329 Changes/New Features in 5.2.12:
330 * ESS[SAS]: `M-;' fixed, but the XEmacs function `comment-dwim' may
331 be broken, if so, use `M-x comment-region' and `M-x
332 uncomment-region' instead; only valid PROCs are fontified which is
333 very helpful finding syntax errors (currently supported: BASE,
334 ETS, FSP, GRAPH, IML, INSIGHT and STAT); the "feature" where
335 `F'-keys take you to an empty buffer when the requested
336 destination is a file that does not exist has been fixed, now the
337 request results in a no-op. Further, sas-mode now also works in
340 * Rterm/Cygwin combination works under Microsoft Windows.
342 * ESS[R]: internal calls use baseenv() instead of NULL and define
343 'baseenv' where needed.
345 * New experimental support for installing ESS. See the file
346 `lisp/ess-install.el'.
348 Changes/New Features in 5.2.11:
349 * ESS Info entry and `dir' handled more effectively for GNU Emacs
352 * ESS[SAS]: temporary files created for batch submission of a region
353 are now named based on the current file; see `ess-sas-file-root'
354 for details; all `lag' and `dif' functions now fontified correctly
356 * iESS[SAS]: fixed a few nagging bugs, however, still does not
357 appear to work at this time; please let us know if you have any
360 * ESS[S]: Support for running other versions of Splus has been added
361 for unix. Two new variables, `ess-s-versions' and
362 `ess-s-versions-list', are used to tell ESS what other versions of
363 Splus you would like to run.
365 Changes/New Features in 5.2.10:
366 * ESS[R]: ess-r-versions can no longer be customized (since the
367 customization was not taking effect unless customizations were
368 loaded before ESS). Its value has been changed so that it will
369 also find R executables beginning "R-devel" and "R-patched". If
370 you wish to change this variable, it must be set in your `.emacs'
371 before ESS is loaded.
373 * Installation with GNU Make enhanced: unix and unix-like operating
374 systems will now be able to install ESS for all users in either a
375 GNU Emacs site-lisp or an XEmacs package configuration by editing
376 `lisp/ess-site.el' and `Makeconf' accordingly, then issuing `make
379 * ESS[S]: Filename completion (inside strings) now also works in
380 XEmacs for R and S-plus.
382 Changes/New Features in 5.2.9:
383 * ESS[R] for Windows: the \ directory character bug with respect to
384 ess-load-file has been eradicated.
386 * iESS[SAS]: `C-c C-r' and `C-c C-b' once again work as intended and
389 * ESS[S]: M-x ess-fix-EQ-assign is a bit more agressive.
391 * ESS[S]: Imenu now also shows setAs(), etc.
393 * ESS[R]: R function pattern enhanced with underlying code such that
394 `M-C-a' (`ess-beginning-of-function') etc now work for many more
395 cases, including S4 method definitions.
397 * iESS[R]: myOwnhelp(1) no longer wrongly triggers help(1).
399 * ESS[R]: Improved detection of bogus help buffers: valid help
400 buffers containing with the string "no documentation"(e.g. contour)
401 were being treated as bogus.
403 * ESS[R]: In R help buffers, if `options("help.try.all.packages" =
404 TRUE)' then `?rlm' will list which packages rlm is defined in.
405 This help buffer is not bogus, but instead is now relabelled
406 "*help[R](rlm in packages)*".
408 * ESS[STA]: add "//" as comment starting character to syntax-table.
410 Changes/New Features in 5.2.8:
411 * iESS: [Tab] completes *file* names "inside string" as in earlier
412 (<= 5.2.3) ESS versions.
414 Changes/New Features in 5.2.7:
415 * If you use Custom to change the variable ess-toolbar-items, the
416 new toolbar is used in all subsequent ESS buffers.
418 * ESS[SAS]: new feature: if ess-sas-log-max >0 and your .log grows
419 to more than ess-sas-log-max bytes, just the first ess-sas-log-max
420 bytes are refreshed; this is helpful when your .sas program
421 generates lots of error messages and gets too big for emacs to
424 * ESS[R/S]: `M-;' in R/S editing modes will now indent with either
425 one or two hashes depending on context.
427 * ESS[R]: David Whiting's Sweave extensions (to 'noweb') are now
428 available (from ess-swv.el loaded by default).
430 Changes/New Features in 5.2.6:
431 * Removed non-ASCII characters in a few files.
433 * ESS[R]: now works better when UTF-8 locale is active; in
434 particular, you get correct directional quotes in R's startup
435 message for R-devel (unstable development version of R 2.1.0)
436 when using environment variables LANGUAGE=en@quot
439 * ESS[SAS]: toggling of .log mode improved (`F10'); toggling of .lst
440 mode now also available (`C-F10'); killing all buffers associated
441 with .sas program no longer bound to `C-F10' since its a bit
444 * S-Plus 7 for Windows is now recognized.
446 * ESS[S] (incl. R): in auto-fill mode, strings are not wrapped
449 * ESS[S] (incl. R): font-lock now correctly differs between R and S,
450 e.g., for "_"; both now fontify warning(.) and S does terminate()
453 * Support for `bell' aka `beep' aka `ding' aka `alarm' in all
454 inferior modes: When \a is output "to the the console" at the
455 beginning of a line, the bell is rung.
457 Changes/New Features in 5.2.5:
458 * ESS[R]: `C-c C-q' or `Quit S' from the menu now should work (again
459 and less klunkily) and do not append `-exited' to the buffer name.
460 Further, the behavior of `(ess-cleanup)', called from ess-quit,
461 now depends on the new customizable variable
462 `ess-S-quit-kill-buffers-p' which defaults to `nil'.
463 Consequently, the question _"Delete all buffers associated with
464 ..?"_ will not be asked anymore by default.
466 * ESS[SAS] - ess-ebcdic-to-ascii-search-and-replace will now work
467 with the `recode' application as well which is available on many
470 * ESS[S] (incl. R): Name completion for slots of S4 objects now
473 Changes/New Features in 5.2.4:
474 * The documentation now includes an overview of how to use the emacs
475 TAGS facility for S functions. (The distribution also used to
476 contain a directory `etc/other/Tags' where a ~1990 version of
477 `etags.c' was distributed; this is no longer relevant and so has
480 * ESS[SAS] - When you are working with EBCDIC files on an ASCII
481 platform, .log NOTEs may display as gibberish since the EBCDIC
482 characters are not converted to ASCII prior to their display. So,
483 the function ess-ebcdic-to-ascii-search-and-replace is provided for
484 convenience and is bound to `C-F11'. This function requires the
485 `dd' command (only available on unix or unix-like platforms).
487 * ESS: Completion of object names is now always done dynamically
488 rather than allowing the option of using a pre-computed database
489 (by `ess-create-object-name-db') since modern computers seem fast
490 enough for dynamic completion. (We expect few users, if any, have
491 been using the pre-computed database method.)
493 * ESS: object completion in iESS buffers running on Windows was very
494 slow (for GNU Emacs, but not XEmacs) and has now been fixed.
495 Further, it was more or less broken for all versions of S-plus 6.x,
496 and has been fixed to work everywhere but with the Windows' GUI of
497 S-plus. The list of objects now shows unique names also when an
498 object appears more than once in the search path.
500 * ESS[R]: Completion of object names now also includes those
503 Changes/New Features in 5.2.3:
504 * ESS: When new inferior ESS processes are created, by default they
505 will replace the current buffer (this restores behavior from pre
506 5.2.0). If you wish new ESS processes to start in another window
507 of the current frame, set inferior-ess-same-window to nil.
509 * New variables inferior-Splus-args and inferior-R-args provide a
510 way to pass command line arguments to starting S and R processes.
512 Changes/New Features in 5.2.2:
513 * bug-fixes for 5.2.1 (require 'executable), html docs, etc.
515 * ess-lisp-directory/../doc/info added to Info-directory-list if
516 ess-info not found by info
518 * ESS[R]: If you have other versions of R on your exec-path, such as
519 "R-1.8.1" with Unix or "rw1081" with Windows, ESS will find them
520 and create appropriate functions, such as `M-x R-1.8.1' or `M-x
521 rw1081', for calling them. By default only Unix programs
522 beginning "R-1" and "R-2" and Windows programs parallel to the
523 version of R in your exec-path will be found, but see
524 ess-r-versions and ess-rterm-versions for ways to find other
527 * ESS[R]: Other versions of R, such as "R-1.8.1" on Unix and
528 "rw1081" on Windows, are added to the "ESS / Start Process /
531 * ESS[S]: If you have other versions of S-Plus on your Windows
532 computer, such as S-Plus 6.1 or S-Plus 4.5, ESS will find them and
533 create appropriate functions, such as `M-x splus61', for calling
534 the console version (Sqpe) inside an emacs buffer. By default only
535 programs installed in the default location will be found, but see
536 ess-SHOME-versions for ways to find other versions of S-Plus.
538 * ESS[S]: Other versions of Sqpe on Windows, such as "splus61", are
539 added to the "ESS / Start Process / Other" menu.
541 * ESS[R]: (bug fix) ess-quit (bound to `C-c C-q') should now quit the
542 inferior R process, when issued from either the inferior buffer,
545 Changes/New Features in 5.2.1:
546 * ESS[S] (R and S-plus): now have toolbar support with icons to
547 evaluate code in the inferior process or to switch there. This
548 code is experimental and likely to change as XEmacs/Emacs issues
549 get resolved. The toolbar should be enabled if your Emacs displays
550 images, but can be disabled with the variable ess-use-toolbar.
551 Thanks to David Smith from Insightful for the S-plus logo.
553 * ESS[SAS]: ess-sas-graph-view (`F12') enhanced; you can specify
554 external file viewers for each graphics file type via the alist
555 ess-sas-graph-view-viewer-alist; also .jpg/.gif are now handled by
556 image-mode on XEmacs, if available, otherwise by graphics
559 Changes/New Features in 5.2.0:
560 * ESS[BUGS]: new info documentation! now supports interactive
561 processing thanks to Aki Vehtari (mailto:Aki.Vehtari@hut.fi); new
562 architecture-independent unix support as well as support for BUGS
565 * ESS[SAS]: convert .log to .sas with ess-sas-transcript; info
566 documentation improved; Local Variable bug fixes; SAS/IML
567 statements/functions now highlighted; files edited remotely by
568 ange-ftp/EFS/tramp are recognized and pressing SUBMIT opens a
569 buffer on the remote host via the local variable
570 ess-sas-shell-buffer-remote-init which defaults to "ssh"; changed
571 the definition of the variable ess-sas-edit-keys-toggle to boolean
572 rather than 0/1; added the function ess-electric-run-semicolon
573 which automatically reverse indents lines containing only "run;";
574 `C-F1' creates MS RTF portrait from the current buffer; `C-F2'
575 creates MS RTF landscape from the current buffer; `C-F9' opens a
576 SAS DATASET with PROC INSIGHT rather than PROC FSVIEW; "inferior"
577 aliases for SAS batch: `C-c C-r' for submit region, `C-c C-b' for
578 submit buffer, `C-c C-x' for goto .log; `C-c C-y' for goto .lst
580 * ESS[S]: Pressing underscore ("_") once inserts " <- " (as before);
581 pressing underscore twice inserts a literal underscore. To stop
582 this smart behaviour, add "(ess-toggle-underscore nil)" to your
583 .emacs after ess-site has been loaded;
584 ess-dump-filename-template-proto (new name!) now can be customized
585 successfully (for S language dialects); Support for Imenu has been
586 improved; set ess-imenu-use-S to non-nil to get an "Imenu-S" item
587 on your menubar; ess-help: Now using nice underlines (instead of
590 * ESS[R]: After (require 'essa-r), `M-x ess-r-var' allows to load
591 numbers from any Emacs buffer into an existing *R* process; `M-x
592 ess-rdired' gives a "directory editor" of R objects; fixed
593 ess-retr-lastvalue-command, i.e. .Last.value bug (thanks to David
596 * ESS: Support for creating new window frames has been added to ESS.
597 Inferior ESS processes can be created in dedicated frames by
598 setting inferior-ess-own-frame to t. ESS help buffers can also
599 open in new frames; see the documentation for ess-help-own-frame
600 for details. (Thanks to Kevin Rodgers for contributing code.)
602 Changes/New Features in 5.1.24:
603 * The version number is now correct even inside ESS/Emacs
605 Changes/New Features in 5.1.23:
606 * Minor more Makefile clean up.
608 Changes/New Features in 5.1.22:
609 * Besides info documentation, PDF and HTML documentation are also
610 provided (instead of built using "make") and available on the web
611 as well; see ESS web page (http://ess.r-project.org/) and StatLib
612 (http://lib.stat.cmu.edu/general/ESS/doc)
614 * Now that info documentation is available, the README.* files are
615 no longer supported. However, they are still distributed for what
618 * ESS is now an XEmacs package! See XEmacs Installation HOWTO
619 (http://www.xemacs.org/Install/index.html) for details
620 (specifically, items 10-15).
622 * ESS[SAS]: more user-friendly enhancements for remote SAS batch
623 jobs with Kermit file transfers (LOG and OUTPUT function key
624 features now supported). Multiple shells now supported so you can
625 run SAS on different computers from different buffers by setting
626 the buffer-local variable ess-sas-shell-buffer to unique buffer
629 * Major re-vamping of Makefile/Makeconf.
631 Changes/New Features in 5.1.21:
632 * ESS[SAS]: info documentation now available!, see ESS->Help for
633 SAS; `F12' opens GSASFILE nearest point for viewing either within
634 emacs, when available, or via an external viewer; more syntax
635 highlighting keywords; more enhancements for remote SAS batch jobs
636 with Kermit; new framework for remote SAS interactive jobs, see
639 * ESS[S]: info documentation now available!, see ESS->Help for the S
642 * Makefile: tag now independent of rel; info files made by
643 doc/Makefile and installed in new info sub-directory
645 Changes/New Features in 5.1.20:
646 * New `options()$STERM' in the S dialects (S, S-Plus, R). The S
647 program can determine the environment in which it is currently
648 running. ESS sets the option to `iESS' or `ddeESS' when it starts
649 an S language process. We recommend other specific values for S
650 language processes that ESS does not start.
652 * New `ess-mouse-me' function, assigned to S-mouse-3 by default.
653 User may click on a word or region and then choose from the menu
654 to display the item, or a summary, or a plot, etc. This feature
655 is still under development.
657 * GNU Emacs 21.1 is now supported (fixed for S dialects, SAS & BUGS),
658 (some from Stephen Eglen).
660 * XEmacs 21.x is now supported (fixed w32-using-nt bug)
662 * XEmacs on Win (NT) is better supported.
664 * Workaround for bug in Sqpe+6 (S-PLUS 6 for Win).
666 * should now work even when imenu is not available (for old
669 * ESS[SAS]: XEmacs-Imenu fix; `C-TAB' is globalized along with your
670 function-key definitions, if specified; you can specify your SAS
671 library definitions outside of autoexec.sas for ess-sas-data-view
672 with SAS code placed in the variable ess-sas-data-view-libname,
673 also the dataset name is defaulted to the nearest permanent dataset
674 to point; Speedbar support now works for permanent datasets, please
675 ignore first./last.; new font-locking is now the default with more
676 improvements for font-locking PROCs, macro statements, * ; and %* ;
677 comments; you can toggle sas-log-mode with `F10' which will
678 font-lock your .log (if it isn't too big); submit remote .sas
679 files accessed with ange-ftp, EFS or Tramp (Kermit is
680 experimental) by setting ess-sas-submit-method to 'sh;
681 ess-sas-submit-command and ess-sas-submit-command-options are
682 buffer-local so you can have local file variable sections at the
683 end of your .sas files to request different executables or specify
684 special options and the local file variables are re-read at submit
685 instead of only at file open so that if you make a change it is
686 picked up immediately;
688 * ESS[BUGS]: font-lock with `in' fixed.
690 * for STATA: font-lock bug fixed.
692 * for Rd mode: `C-c C-v' and `switch-process' in menu. further,
693 `C-c C-f' prefix (Rd-font) for inserting or surrounding a word by
694 things such as \code{.}, \code{\link{.}}, \emph{.} etc.
696 * new functions (ess-directory-function) and (ess-narrow-to-defun)
697 ess-directory <-> default-directory logic (Jeff Mincy).
699 * Re-organized Makefile and fixed a few bugs.

702 * S+6 now supported (Tony Rossini (Unix) and Rich Heiberger
705 * New BUGS support through ESS[BUGS] mode (Rodney Sparapani)
706 Templates assist you in writing .bug and .cmd code (.cmd and .log
707 are replaced by .bmd and .bog to avoid emacs extension collisions).
708 Substitution" parameters facilitate "automagic" generation of
709 data...in" and "init...in" filenames, "const N=" from your data
710 file and "monitor()/stats()" commands. Activated by pressing
713 * Fixes for `ess-smart-underscore' SAS breakage (Rich Heiberger)

721 the new functionality, set ess-sas-run-make-regexp to nil. Also
722 available in .log files via `F10'.
724 * Open a permanent SAS dataset for viewing via `F9' (Rodney
725 Sparapani) You must have the library defined in autoexec.sas for
728 * User-friendly defaults for `sas-program',
729 `ess-sas-batch-pre-command' and `ess-sas-batch-post-command' as
730 well Customize support for these and other ESS[SAS] variables
733 * `ess-sas-suffix-2' now defaults to .dat via `F11' (Rodney
736 * Emacs/XEmacs, Unix/Windows issues collectively handled in
739 * defadvice solves problem of missing *ESS* (thanks to Jeff Mincy)
741 * Improved manual a bit by including things that were only in
744 Changes/New Features in 5.1.18:
745 * New `ess-smart-underscore' function, now assigned to "_" by

747 inside string and comments where plain "_" is used instead. (MM)
749 * Fixes for longstanding interactive SAS breakage (RMH)
751 Changes/New Features in 5.1.17:
752 * Documentation for Windows Installation (Rich Heiberger)
754 * removal of ess-vars, finalization of customize support (in the
755 sense that there is no more use of ess-vars, but that we need to
756 fix ess-cust) (AJ Rossini)
758 * Many small (and large) fixes/contributions (MMaechler)
760 * addition of the "S-equal" variable and provide `M-x
761 ess-add-MM-keys' a way to remap "_" to `ess-S-assign', typically "

822 * able to use inferior iESS mode to communicate directly with a
823 running S-Plus 4.x process using the Microsoft DDE protocol. We
824 use the familiar (from Unix ESS) `C-c C-n' and related key
825 sequences to send lines from the S-mode file to the inferior S
826 process. We continue to edit S input files in ESS[S] mode and
827 transcripts of previous S sessions in ESS Transcript mode. All
828 three modes know the S language, syntax, and indentation patterns
829 and provide the syntactic highlighting that eases the programming
