   Hi - Sorry to divert this thread, but....
   
   I have a similar problem, using Xemacs 21.1.9 and R1.3.1. But when starting
   xemacs, I get the following in a *Warnings-Show* buffer:
   
   "(1) (initialization/error) An error has occurred while loading ~\.emacs:
   
   Symbol's function definition is void: w32-shell-dos-semantics


essnt204 is not getting loaded.  This was my fix.

(when (eq system-type 'windows-nt)
  (autoload 'w32-shell-dos-semantics "essnt204"))

   ...
   
   in .emacs as was suggested, I get closer but the *R* buffer shows:
   
   "WARNING: unknown option --no-readline
   Fatal error: you must specify `--save', `--no-save' or `--vanilla'
   

I think this was fixed in the 5.1.19 ess release.


from essd-r.el in the ess lisp directory you need to have the 'mswindows check.

(defun R (&optional start-args)
  .....
  (let* ((r-always-arg
	  (if (or (equal window-system 'w32)
		  (equal window-system 'win32)
		  (equal window-system 'mswindows))
	      "--ess "
	    "--no-readline "))
