[babel] Passing of variables to R - usage of temporary file not ideal for tangling

[babel] Passing of variables to R - usage of temporary file not ideal for tangling

I just realized that babel is using temporary files when passing
tables to R (no idea about other languages). This is OK when
evaluating code blocks or exporting, but causes problems when
tangling, as the temporary files are not available in a new session
and handing on the tangled code or sourcing it from R becomes impossible.

I would therefore suggest to change the mechanism of passing tables to
R so that the tables are included in the tangled files.

One option would be to use a direct 'text-connection' as describer in
the R help of read.table(), last example.

Cheers,

Rainer

there has been a thread about this about two years ago:

Must have missed that one - I might take a look at this issue, but it
s not a major issue for me at the moment.

As it was for me during the last two years ;-)
