Sorry for hijacking this thread. But I am also interested in backend
specific options. Could you give an example of how to achieve something
like this with the new exporter:
#+begin_src R :results graphics :file (if (and (boundp 'org-export-current-backend) (eq org-export-current-backend 'e-latex)) "foo.pdf" "foo.png")
plot(1:10)
#+end_src
Thanks in advance,
Andreas
