[Orgmode] Re: Babel: interweaving code and results?

[David Hajage]

exactly what I want! But an new option would be greater...

Yes, I know about :exports both, but if code and results are interleaved, I don't need to export the code (in my case). That's why I use :exports results.

Thank you very much for this.

Hi David,

This is actually quite easy, although I don't think anyone's flagged
this possibility up: just do

(setq org-babel-R-command "R --silent --no-save")

(Our default is --slave --no-save) There's an example session below. By
the way, can I just check that you're aware of the ':exports both'
option? That's the canonical Org way of exporting both code and
results. It doesn't interleave them: it's more geared towards 'one code
block <-> one result'. But I understand that there may be situations
where interleaved is desired.

Erik -- You might well be right that we should add an :interleave option
to modify :results output like this.

--8<---------------cut here---------------start------------->8---
#+begin_src emacs-lisp
org-babel-R-command
#+end_src

#+results:
: R --slave --no-save

#+begin_src R :results output
2+2
3+3
#+end_src

#+results:
: [1] 4
: [1] 6

#+begin_src emacs-lisp
(setq org-babel-R-command "R --silent --no-save")
#+end_src

#+results:
: R --silent --no-save

#+begin_src R :results output
2+2
3+3
#+end_src

#+results:
: > 2+2

: [1] 4
: > 3+3
: [1] 6

[Maybe we can battle that trailing prompt character]
