[Martin Maechler]

Thanks a lot, Frede, 
for your "community help"!

I have one remark (below).

An alternative way, which I slightly prefer is to 
customize  inferior-R-args  by adding "--no-save" to it.

[hackerishly: add the following line at the proper place
	      namely inside " (custom-set-variables .. ) "
 to your ~/.emacs file :

 '(inferior-R-args "--no-save ")

]

The slight advantage of this approach is that ``R can now'' that
this is set, e.g.,  via  commandsArgs()

Note, Patrick that you possibly also want to add
"--no-restore-history" or even "--no-restore" to that list of R 
command line arguments.
