For something simple like this, I'd use:

,----
| #+PROPERTY: session *R*
| #+PROPERTY: results output
| 
| #+NAME: image
| #+HEADER: :results graphics
| #+HEADER: :exports results
| #+HEADER: :file (org-babel-temp-file "./figure-" ".pdf")
| #+BEGIN_SRC R
|   x <- rnorm(100)
|   caption.string <-
|     sprintf("The mean value is %.3f.\n",mean(x))
|   hist(x)
| #+END_SRC
| 
| 
| #+CAPTION: src_R[:results raw]{ cat(caption.string) }
| #+RESULTS: image
`----

For more complicated stuff I use ravel[1] to export as *.Rnw and then use
knitr on the result.



HTH,

Chuck
