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
