| Ok, the following works: --- (kbd-map ("C-8" (let* ( (f (url-concretize (url-temp))) (p (open-output-file f)) ) (write (selection-tree) p) (close-output-port p) (eval-system (string-append "convert_pb2R.pl " f)) ) ) ) --- This will save the current selection to a temporary file, then run convert_pb2R on it. convert_pb2R will then put the converted text onto the clipboard, which then I can insert into the buffer. This still uses the command pbcopy to put the string back into the selection buffer (though it should be possible from TeXmacs), and analyzing the tree from withing TeXmacs would be much more elegant...
Comments welcome. Thanks!

I'm not sure if it could help, but in a recent post about bookmarks I posted some scheme code which lists all tags of a given kind in a document. Might this not be used to list all the R input lines? Just a possibility, I wouldn't know...
Here is my feeble attempt:
(kbd-map ("C-8" (for-each (lambda (item) (display (tree->string (tree-ref item 0)))) (selection-tree) ) ) )
But, it doesn't work. I get an error: In procedure for-each in _expression_ (for-each (lambda # #) (selection-tree)): Wrong type argument in position 2: <tree <math|x<rsup|2>> Hello>
Which is kind of funny, since the error statement contains the string I'd like to get :) all I want is a string like that:
<tree <math|x<rsup|2>> Hello>

P.S. Just a comment. I think there is a bug in the scheme session, in that expressions such as "tree->string" are converted to "tree-<gtr>string", and then you get an error that that function is not defined.

I managed to do what I asked for, though it is a hack, and currently only works on a mac.
Attached is a perl script. It should be saved as convert_pb2R.pl somewhere in the path.
Then, add this to my-init-texmacs.scm:
(kbd-map ("R R ." (shell "convert_pb2R.pl")
(clipboard-paste "primary")
))
What you can do then is select several input/output cells in an R session (or even several R sessions). Copy them.
Then go to the place you want to insert them (for example an empty input cell) and type "RR.". TeXmacs will insert only the R commands in the copied cells.
