How to end a :session?

How to end a :session?

[Rainer M Krug]

[-- Attachment #1: Type: text/plain, Size: 1600 bytes --]

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
http://orgmode.org/manual/session.html

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)
  (sleep-for 1)
  (kill-buffer))
#+end_src


#+call: killRsession("*myR*") :results none
--8<---------------cut here---------------end--------------->8---

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.
