It states to find customization you type M-x customize-group ret ess. I access a file which invokes ess (a SAS source) and do this, which brings up the various customize dialogs. I looked for R, and find it as a dialect of S.

It is kind of a mess (which is the reason why I usually avoid it).
However, in this case, there is an easy way out.  Just do
F1 v ess-directory-containing-R

At the bottom of the generated *Help* buffer, you should see:

You can customize this variable.

The word customized is underlined and clicking on that launches
you into a customize buffer
*Customize Option: Ess Directory Containing R*
where you can do your worst ;o)
