That explains.

OK - it is working.
What I actually did, was to add

   #+BABEL: :comments yes

to the headers of the file, so I can control it on a file basis.

Definitely.

Both points agreed.

In addition: is it possible to customize the format for all comments (on a
per file basis and / or a per block basis)? i.e. I don't need the file name,
as all blocks are coming from one file. I know about

  #+srcname: <name>

but is there a variable for the line number (I guess that is covered by the
request posted in another thread) one could use?

Also, would it be possible to include a link in the comment block, so that
clicking on that link actually opens the org-file file at the location of
the source block? That would make editing the code really easy.

Thanks for helping to sort some of these issues out!

Pleasure - I use them and I profit when they are sorted out. In addition: I
think org-mode and babel deserve it - they are great tools for programming
in R.
