And the way I actually do this is by putting the following in my .emacs
(setq R-editor "/Applications/Emacs.app/Contents/MacOS/bin/emacsclient")

Btw. when I now do something like fix(print.lm) I get the following  
"error" - I use quotation marks because it seems to work fine...
     inferior-ess-send-input: Wrong type argument: number-or-marker- 
p, nil
(this is from the *Messages* buffer)
