[R] How to run R on Emacs+ESS

[Stephen Liu]

Hi Steve,

Thanks for your advice.

appending the /sw/bin directory to the exec-path and PATH variables (useful for 
Mac OS X users running LaTeX):
(setenv "PATH" (concat (getenv "PATH") ":/sw/bin"))
(setq exec-path (append exec-path '("/sw/bin")))


On which file shall I add above command lines?

On terminal running;
$ which R
/usr/bin/R

Whether replace /sw/bin with /usr/bin


Or run above 2 lines on terminal?  TIA

If fail I'll remove the running Emacs and ESS and reinstall version 5.11

I believe the latest version is 5.11 -- you might want to try that.

Others my not agree with me, but I'd just try to install it w/o using
debian's package manager. ESS is actually very easy to install just by
downloading the latest release and following the install instructions.

As long as you have a running version of R (executed by running `R`
from you command line), the `M-x R` should work.

Actually, for that to work, the path for your R executable needs to be
in emacs' exec-path:
http://www.emacswiki.org/emacs/ExecPath

I think it should (by default) pull in the dirs in your $PATH variable.

Also ...

Doesn't this (emacs starting w/ 2 "boxes) usually happen when there is
some error while running emac's init code (somewhere in your .emacs
file, or another file it links to)? Unless, of course, you explicitly
make it do so but it doesn't sound like that's the case.
