[ESS] Using ssh from within emacs 22 to connect to another computer and run ess-remote

[Kasper Daniel Hansen]

I may be completely outdated, but this is what I do.

Start a shell inside Emacs (M-x shell ). Switch to shell process and  
ssh to the appropriate server. Start R. Now execute ess-remote (M-x  
ess-remote). This tells Emacs/ESS that the shell process is really  
just an R process. You now have R running.

Only caveat was that last time I used it (and that is some time ago),  
sometimes C-c C-c would stop the ssh connection instead of just  
stopping R.
