Hi Tom,

thanks for this answer.  This indeed comes closer to what I want.

But, some comments:

(1) There seems to be an error in the manual:
In the manual the :noweb tangle header argument is given as :noweb yes,
which is why I missed that option.

(2) The noweb link are expanded *always* (i.e. execution, export,
tangle) even with the :noweb tangle option:
  #+srcname: mod1
  #+begin_src R :tangle no :export code
    print("mod1")
  #+end_src

  #+srcname: mod2
  #+begin_src R :tangle no :export code
    print("mod2")
  #+end_src

  #+srcname: part1
  #+begin_src R :noweb tangle :tangle yes :export code :session *R*
    <<mod1>>
    <<mod2>>
  #+end_src


(3) I am looking for an option to disable the noweb link expansion
during *export* only.  However, as I understand it, the :noweb tangle
header option is supposed to disable the expansion also for *execution*.


So, is this not possible right now?

Cheers,
Andreas
