issues with export of LaTeX figure captions

[RJ Cunningham <robut@iinet.net.au>]

G'day fellow orgmode users,

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

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
 2. it is ugly to have the caption sandwiched between the code and the
 results
 3. often, but not always, when the code is re-executed the caption and
 label is lost

I also see that HTML export also fails to produce a caption.


Is this an issue in orgmode that can be addressed or is it an issue with
my understanding? I must admit as much as I like org-babel I have long
found the options for headers and arguments hard to understand well.


Cheers,

Robert Cunningham
