Hi
I would like to do make the file header argument to be concatenated of a constant string and
another variable, so effectively:
#+header: :var+ ConNum="10"
#+header: :results graphics
#+header: :file SA_VALUEOFConNum.pdf
#+header: :width 8
#+header: :height 8
#+header: :pointsize 8
#+begin_src R
plot(runif(100))
#+end_src
#+RESULTS:
[[file:SA_10.pdf]]
Is this possible?
Thanks,
Rainer

Hi Rainer,
I am not aware of any method that directly does what you want. But depending on
where the value of your variable ConNum is coming from, the
following might be a start for you. It is based on the possibility to
insert elisp in the header arguments:
#+name: myconnum
- 19
#+header: :var ConNum=myconnum
#+header: :results graphics
#+header: :file (concat "SA_" (sbe myconnum) ".pdf")
#+header: :width 8
#+header: :height 8
#+header: :pointsize 8
#+begin_src R
plot(runif(100), main=ConNum)
#+end_src
#+RESULTS:
[[file:SA_(19).pdf]]
Best,
Andreas
