Hi
I can start a session as follow:
--8<---------------cut here---------------start------------->8---
#+begin_src R :session Test
cat("Session Test\n")
#+end_src
--8<---------------cut here---------------end--------------->8---
Now I hava an R session named *Test*. But how can I closes this session?
I thought about just quitting R
--8<---------------cut here---------------start------------->8---
#+begin_src R :session Test
q(save = "no)
#+end_src
--8<---------------cut here---------------end--------------->8---
but this does not return as ESS is waiting for the prompt (">").
Is there a way of closing the session *Test* and close the buffer?
My reasoning is that I want to do different longer analysis in one org
file and start each in its own session, i.e. clean R. But as they
involve several steps, I don't want to put them into one code block.
So I have several code blocks which I want to execute in a "throw away
session" which I would like to discard afterwards.
So I am looking for something like
#+CLOSE_SESSION Test
which would then close the session *Test*
Is something like this possible at the moment?
Rainer

perhaps what you want is a named session, see

Sure - that's what I have.
But how can I close the named session when I don't need it anymore, or
want to start, the next time I use the named session, with a new
session?

How about
--8<---------------cut here---------------start------------->8---
#+name: killRsession
#+begin_src emacs-lisp :var rsession="*myR*" :results none
(progn
(switch-to-buffer rsession)
(ess-quit)

Thanks - this works. But I get an error which says:
,----
| save-excursion: Wrong type argument: integer-or-marker-p, nil
`----
Any suggestion on how to avoid this?
Thanks,

I do not see that error, so hard to say. Do you have a backtrace? Wild
guess: Maybe the ess-quit changed? What version of ess are you using?
Note, that this could be improved by replacing the (sleep-for 1) with
something that actually waits until R has quit...

I can live with the error for now, but I might look into it some time
later.
