[R] getting ess/emacs to link with a remote instance of R

[Mark W Kimpel]

Seth,

Thank you for your response, every worked exactly as you described it, 
even the fact that ?help does not work very well with a remote session. 
I will probably open up a separate emacs window with a local R process 
to access help functions.

I didn't know about the ess-help, I had checked out emacs-help but, 
looking at an archive, it looked like it had very little activity over 
the past two years. Maybe I was mistaken?

Thanks,

Mark
