[ESS] ess-remote trouble

[Matthew Keller]

Hi all,

At this very moment, I came onto the ESS help boards because I was
having this same issue, and lo and behold, a post about it 9 minutes
ago! (What are the chances of that??)

I am currently using
1) M-x shell
2) ssh -XC user at host
3) R
4) M-x ess-remote <r>

I did this for two different processes. I had to rename the first one
"Session2" so that commands would go from the appropriate .R buffer.
About 10 minutes into this, the prompt on the first buffer stopped
working.

This is but one of many problems I've had using M-x shell and so I'm
ready to move on to other alternatives for using emacs remotely.

Could someone either explain how to get around this M-x shell issue,
or direct me to simple instructions for how to use tramp? I don't
understand exactly what to do to start tramp up and how to use it. Any
help would be appreciated...

Matt
