I asked this question on Stack Overflow today, I wonder if someone might know the answer here:
http://stackoverflow.com/questions/9215216/computing-argument-values-dynamically
It's about computing arguments to a "#+begin_src R" block based on previous R results.
Thanks.

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
