org-babel-R: export R graphics to LaTeX

[Gary Oberbrunner <garyo@oberbrunner.com>]

I have the following org-mode test file:

===========
#+TITLE:    tester.org
#+PROPERTY: session *R*
#+PROPERTY: results output
#+LaTeX_HEADER: \usepackage{hyperref}

* Headline here

Here is some text.

#+begin_src R :exports both :results graphics :file img.jpg
hist(rnorm(100))
#+end_src
=============

and exporting it to LaTeX with C-C C-e d gives a PDF with only a link
to the graphics file, not inlined as a figure.  How do I include the
actual R graph?
