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. > 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.

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. > 3. often, but not always, when the code is re-executed the caption and > label is lost Can you provide an ECM for this? > I also see that HTML export also fails to produce a caption. Confirmed, in a 1-min test. Though, I had the impression that captions were handled in ox-html.
