[ESS] assiciation to ESS-R process

[Andreas Leha]

Hi all,

I have a simple question concerning the association of a buffer editing
a .R file and an ESS-R process.

Whenever I open a .R-file, it is not associated (as indicated by
[none]).  The association happens only as soon as I evaluate something
or run ess-switch-process.

Now my question:
I am looking for a function that I can run (or buffer-local variable I
can set) to associate the buffer to an R session of a given name.  If an
R process with the given name does not exist it should be started.

Is such a function available?

Regards,
Andreas
