Hi Ken, I think you can not extract variables from underlying processes (like R) in org. What you can do in your example, however, is (1) name the first source block (2) call it with sbe (3) do the calculation in emacs-lisp which would look something like this: ,----[ example ] | #+name: setheight | #+begin_src R | x <- 5 | #+end_src | | #+begin_src R :results graphics :file foo.svg :height (* 3 (string-to-int (sbe setheight))) | plot(1:10) | #+end_src `---- Cheers, Andreas
