[ESS] assiciation to ESS-R process

[Andreas Leha]

Hi Rodney,

thanks for looking into this.  The hook works, but I do not see, how I
could specify the name of the R session - it is hard-coded into the hook
then, right?

Just for the background: I am asking because I use org-mode, which has
the nice feature of allowing multiple R sessions (defined by a destinct
name).  In org-mode the R-code is encapsulated in source-blocks of this
form:
#+begin_src R :session foo
   print("some R code here")
#+end_src
This example block will be executed in the R session *foo*.
Now, when the cursor is inside the source-block and C-c ' is pressed, a
new buffer in ESS mode is presented with the source code only.  And I
would like this buffer to be associated to the R session *foo* right
away.  As soon as I evaluate some code from this new buffer, it is
associated with the correct R session, but before that all (completion)
functionality is not available.
In order to get org-mode fixed in this respect, I'd need to know how to
get such association.

Regards,
Andreas
