I would strongly suggest upgrading to R 1.2.2, which no longer needs
to set the explicit memory limits.

>From ESS, there is an example of how to set it in the file essa-r.el
in the distribution:

;; you can invoke ESS/R from emacs by typing
;;      C-u M-x essr
;; with vsize set to (for example) 40M, and nsize set to 600000.
(defalias 'essr
  (read-kbd-macro
     "C-u M-x R RET - - vsize SPC 40M SPC - - nsize SPC 600000 2*RET"))
;; "SPC" must be "=" in future versions of R (works from 0.99 on)

And then 
        M-x essr 
does what you want.

Neither solution is ideal, but both work acceptably.

best,
