Hi RJ,

I've encountered an issue/difference with the way the recent babel
processor handles captions.
In versions prior to 8 the following WORKED (on export produced a figure
environment with a caption):
#+CAPTION: Fails to produce table environment and so caption in the new
orgmode
#+LABEL: fig:fails
#+begin_src R :session :results graphics :file fails.pdf :exports results
plot(1:10)
#+end_src
Side-remark: I find it weird, if not uncorrect, to have the header argument
:session empty. IIRC, this is, at best, dangerous, because it could
interpret what follows as its value.
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.
Under orgmode version 8.0.2 (8.0.2-2-g93da18-elpa the same code does
not work, the includegraphics is exported sans the figure environment.
Under this latest orgmode the following does work:
#+begin_src R :session :results graphics :file ok.pdf :exports results
plot(1:10)
#+end_src
#+CAPTION: Succeeds to produce table environment and so caption
#+LABEL: fig:OK
#+RESULTS[2d39a23f088d95e808bb867f97a0ecd2df621bbd]:
[[file:ok.pdf]]
However, this second construction of code has the following issues:
1. it is different to prior method which worked
Yes, a lot of changes have been made in Org 8. This is for good, even if the
switch can be somewhat painful.
Indeed.
2. it is ugly to have the caption sandwiched between the code and the
results
Not really. Please well think that there are two different beasts here: the
code block and the results block. You can export both, and you could attach
(different) captions to both. So, that does not seems that illogical to me.
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.
3. often, but not always, when the code is re-executed the caption and
label is lost
Can you provide an ECM for this?
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
#+LABEL: fig:OK
#+RESULTS:
[[file:ok.pdf]]
:cache no is fine
Cheers,
Robert
