I thought the following would work:

;; (tool-bar-mode 0)                 ;no tool bar thanks.
;; (add-hook 'ess-mode-hook 'my-ess-toolbar-hook) 

;; (defun my-ess-toolbar-hook ()
;;   (tool-bar-mode 1))

but it didn't -- tool-bar-mode turns it on globally.  So, there may be a
solution, but its not obvious, sorry.
