Xemacs/ESS on Mac OS X

[Rodney Sparapani]

Christof:

You can't use xemacs with R on Mac OS since xemacs does not support AppleScript. 
Currently, only Emacs supports it.  Emacs 21.1 is available for OS X.1, but you 
have to patch it.  See http://mac-emacs.sourceforge.net/
You will also need the attached AppleScript patches.  Also, note that R on Mac 
only supports batch processing via AppleScript at this time.

>I'm new to the Xemacs/ESS world. I recently installed XEmacs 21.4 on my 
>Mac (OS X), which looks fine in X11. Since I want to run R with ESS 
>5.1.19, I installed this package, too, without changing anything in the 
>'ess-site.el' file.
>After starting up XEmacs, I get the following error (besides of some 
>keymapping/warnings):
>
>> (1) (initialization/error) An error has occurred while loading 
>> /Users/christof/.xemacs/init.el:
>>
>> Invalid byte code: "variable reference to constant symbol :group"
>> ...
>
>The content of the init.el file is:
>
>> (load "/sw/lib/xemacs/site-lisp/ess-5.1.19/lisp/ess-site")
>
>which is the path to the ess-site.el file.
>
>The content of the .emacs file is:
>
>> ;;; XEmacs backwards compatibility file
>> (setq user-init-file
>>       (expand-file-name "init.el"
>>                         (expand-file-name ".xemacs" "~")))
>> (setq custom-file

>> (setq ess-ask-for-ess-directory)

>> (load-file user-init-file)
>> (load-file custom-file)
