Putting this in ess-mode-hook will also work.

In my opinion this is not the best idea. Emacs is keyboard oriented
software, and if you modify something as fundamental as syntax table for
the sake of a mouse click convenience, you are likely making a move in a
wrong direction.

Emacs word movement commands (M-f, M-b) will not stop at _. For people
who use "_" in their programming (like myself), that would be extremely
annoying.

Have you considered M-f M-f as an alternative for a mouse click?
