I can't get C-q C-c to work. All it does is print: > ^C on a new line in the R process. What Emacs/ESS were you using for those that got this to work? I am using Aquamacs Emacs 23.3 on Mac OS 10.8.2 and opening a terminal in emacs -> ssh to remote Linux cluster -> starting R -> M-x ess-remote -> C-q C-c Thanks, S
