[O] Graphics in LaTeX pdf output.

[Neuwirth Erich]

I am trying to produce pdf through latex with R in org.
I am using MacTeX 2012, Emacs 24.2, and org mode version 7.9.1 (on Mountain 
Lion)

I have the the following code segment.


#+BEGIN_SRC R :session *R* :results output graphics :file first.png :exports 
both
plot((0:10)^2,type="l")
#+END_SRC


It does not work.
It produces text output and then stops.
When I run latex on this manually, TeX complains about a missing bounding box.

! LaTeX Error: Cannot determine size of graphic in agegraph.png (no BoundingBox
).

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...                                              
                                                  
l.863 ...raphics[width=.9\linewidth]{agegraph.png}

html output works.

I dimly remember that the same file worked with a previous version of org and 
MacTeX 2011.
