I guess it could be dangerous, though it is convenient and I don't
believe it has ever caused me any issues. I note that at one time, at
least, a name was an optional argument for the :session header (see
http://www.jstatsoft.org/v46/i03/paper p 10). I will consider being less
weird though as you suggest.

Indeed.

OK, that is not something I have ever needed but I see that it would
make sense in such a situation. Is there any way that I can export
figures with captions WITHOUT having to execute the code and capture the
results in the org file. With the previous construction the caption was
added to the executed code results on export-so reducing the clutter in the
org file by not having the results in the org file.

The problem seems to relate to :cache
This gobbles up the caption and label.
#+begin_src R :session :results graphics :file ok.pdf :exports results :cache yes
plot(1:10, col="blue",cex=1)
#+end_src
#+CAPTION: Succeeds to produce table environment and so caption XXXX
#+LABEL: fig:OK
#+RESULTS:
[[file:ok.pdf]]
:cache no is fine
Cheers,
Robert
