Hi Mark,

[I've cc'd the ess-help list and any further discussion should probably

1. Start a shell inside Emacs using 'M-x shell'.  In this shell, ssh
   to your remote host and start R.

2. In the remote R session do: 'M-x ess-remote'.  At the Emacs
   mini-buffer prompt type 'r'.

3. In a buffer containing R code, you should be able to send code to
   the remote session as usual (choose the shell buffer when


  * C-c C-c will kill your ssh session (and R).  IOW, you can't easily
    interrupt an R process running remotely.

  * I have never had success getting help to work via ESS when running
    R remotely.  YMMV.

  * You may find that sending commands to the remote session without
    echoing is much faster.  So you might try C-u C-c C-r to send a
