Hi Jianjie:

The function run-mode-hook does not exist and also, does not appear
anywhere in the ESS sources that I can find.  The function name is
run-mode-hooks.  But, the error must be some where in the lisp files
distributed with the version of Emacs that you use.  Try upgrading
Emacs.  Hope this helps.
