[ESS] Sweave helper function

Hi ESS-ers,

I find that in using Sweave the thing that I forget most often is how
to set up the graphics environment properly.  Inevitably I go back
through old files to remind myself.  Well, no more!  I have added the
following function to my .emacs file:

(defun ess-insert-Sweave-figure ()
   "Insert Sweave Figure into the buffer at next line."
   (insert "
<<label=myfig-code, include=FALSE>>=


<<fig=TRUE, echo=FALSE, eval=TRUE, width=6, height=6, label=myfig>>=


(define-key noweb-minor-mode-map "\M-nf" 'ess-insert-Sweave-figure)

My questions are 

1) does anyone know how I could hack this so that if a region were
marked, that region would be used as the seed of the labels?  I guess
I want to grab the marked region as an argument, and use that instead
of myfig everywhere above.

2) is this overkill?  Is there a more emacs-y way of solving my

Thanks for any thoughts!
