Unfortunately, using the versions of ess-mode.el and ess-r-mode.el 
referenced above doesn't work for me.  I get the following warning when 
starting Emacs:

Warning (initialization): An error occurred while loading 
‘c:/Users/henwin/.emacs’:

Wrong type argument: stringp, (lambda (&rest --cl-rest--) Start this 
process version in an inferior ESS buffer.
Function defined using `ess-define-runner'. (interactive P) (apply 
(quote (lambda (G0 G1 G2 &optional start-args) (cond ((string= 
(symbol-value G1) R) (let ((inferior-ess-r-program (or (symbol-value G0) 
(symbol-value G2)))) (R start-args))) ((string= (symbol-value G1) S) 
(let ((inferior-S+-program (or (symbol-value G0) (symbol-value G2)))) 
(require (quote ess-sp6-d)) (S+))) ((string= (symbol-value G1) SAS) (let 
((inferior-SAS-program (or (symbol-value G0) (symbol-value G2)))) 
(require (quote ess-sas-d)) (SAS)))))) (quote --path--) (quote 
--dialect--) (quote --name--) --cl-rest--))


When byte-compiling ess-r-mode.el I get the following:

Compiling file c:/Users/henwin/Desktop/ess-r-mode.el at Mon Jul  2

In ess-r-define-runners:
ess-r-mode.el:668:41:Warning: ess-define-runner called with 3 arguments, but
     accepts only 2
ess-r-mode.el:668:78:Warning: function ‘mapcar*’ from cl package called at
     runtime



Best,
Henric
