Thanks for pointing me to RTFM - there I found "drawer" and

,----
| #+begin_src R :results  raw drawer 
| c("*** Mean", "[[file:./netimpacts_mean.pdf]]","", "*** Mode","[[file:./netimpacts_mode.pdf]]")
| #+end_src
`----

results in

,----
| #+RESULTS:
| :RESULTS:
| *** Mean
| [[file:./netimpacts_mean.pdf]]
| 
| *** Mode
| [[file:./netimpacts_mode.pdf]]
| :END:
`----

which is nicely highlighted as headers, exported as headers and
replaced.

Perfect.

I don't quite understand your code below and what it is supposed to do.

Thanks,

Rainer
