Thanks Stephen

I am a slightly bit confused here.  I am pretty indifferent regarding the fact that ssh.el is not part of Emacs (but I was wondering...).  Are you suggesting term mode because it will be easier to solve my problem using term mode or just because term mode comes with Emacs?  It might not be that hard to write ssh-send-string using term-send-string as a template.

When I do use term mode I can start up R-devel on the remote cluster.  But when I execute ess-remote, Emacs (22 in this case) complains "error in process filter: Symbol's value as variable is void: term-pending-delete-marker", after which I can move around in the terminal buffer, but not get contact with the R process at all.  It seems that ess-remote is really designed for use with ssh.el?
