Ah, that might be the problem.  I'm not sure M-x ess-mode is defined
to turn on a particular mode.  e.g. if you want the current buffer to
be R mode, you should do M-x R-mode  (and of course if the buffer
filename has suffix .R or .r it should do this automatically).

What buffer were you currently in and what did you expect to happen/
