After studying and trying your suggestion, I have to say that it works, 
produces more smooth output scrolling, and keeps the ESS code untouched.

In the end, I did change my .emacs file, indirectly, using the 
customization setup for the 'comint' group. Here is the relevant part of 
the configuration:

   ;; custom-set-variables was added by Custom.
   ;; ...
   '(comint-move-point-for-output (quote others))
   ;; ...

The variable 'comint-scroll-to-bottom-on-output', that you mentioned 
above, is an alias for 'comint-move-point-for-output.'
