I'm not sure how customizable other emacs toolbars are.  But as far as
ESS goes, currently the toolbar is not dynamically modifiable during a
session.  If you change a ESS toolbar var, you have to restart Emacs
to see its effect.

Thanks; this string "no other R or Sqpe versions" helped me find the
problem easily; I get the same behaviour.  This is a bug in 5.2.2, and
I'm surprised if anyone (not just you) could get the R button to work
in this version.  I have now fixed it, so either wait for the next
version, or if you are feeling brave, edit ess-mode.el (and delete
ess-mode.elc) as follows:

line 230 should read:
     ["No other R or Sqpe versions" R nil])

change it to:

     ["No other R or Sqpe versions" nil nil])

and restart Emacs.  Fingers crossed.
