ok, here is a suggestion:

(defun ess-r-set-width ()
  "Set width option for R based on current window width.
Only sensible when called from within an *R* buffer."
  (let ((wid (window-width)))
    (ess-command (format "options(width=%d)\n" wid))
    (message (format "Window width set to %d" wid))))

& for those who want it automatically updated:

(add-hook 'inferior-ess-mode-hook
	  '(lambda ()
	     (add-hook 'window-configuration-change-hook
		       'ess-r-set-width nil 'local)))
