I cannot provide a fix for your problem because I don't know what is
inside the /home/me/bin/R.csd3. This file seems to be on your localhost
isn't it? but as a way around the problem you can try
- ssh to the remote host (outside of emacs)
- start screen session
- detach it
- open shell in emacs (M-x shell)
- ssh to the remote host again in the emacs shell
- resume the screen session (screen -r)
- start the version of R of your preference
- finally attach ESS to the R process using M-x ess-remote in the shell buffer where you started R
Hope this helps,
