command line arguments to R

[Stephen Eglen]

The current development version of ESS has a new variable,
inferior-R-args, that allows you to set command line args to pass to
R.  This is in response to recent requests on the list (e.g. from Andy
Liaw and Pierre Kleiber):

 > I normally get R started within ess using a bash script containing:

So, to answer Pierre's email, with the latest version, you can now do:

emacs --eval='(let ((inferior-R-args "-q --no-save")) (R))'

or just put (setq inferior-R-args "-q --no-save") in your .emacs.

As a reminder:

To get the latest development version of ESS, you need a the
subversion client `svn' configured with `--with-ssl' support.  You can
then do:

%  svn checkout https://svn.r-project.org/ESS/trunk ess-svn
