[ESS] toggle between R versions

Alright, I must be awfully close. Here is my insert into my .emacs
(setq exec-path (cons
(expand-file-name "~/R_HOME/R-devel/R-build/bin")
(cons
(expand-file-name "~/R_HOME/R-current/R-build/bin")
exec-path)))
Whichever ver of R I put inside the first expand-file-name is the one
that is executed when I hit the "R" icon or "R" under "start process".
With "start process > other > R-newest" nothing loads with either try.
Is there something wrong with my Lisp code?
