This can be done system wide by setting the language-specific header arguments.
I've yet to see an example on how to do this.
#+begin_src emacs-lisp (setq org-babel-default-header-args:R '((:session .
"org-R"))) #+end_src
#+RESULTS: | (:session . org-R) |
#+begin_src R x <- 1 x #+end_src
#+RESULTS: : 1
#+begin_src R x #+end_src
#+RESULTS: : 1

Okay, that's the expected usage. How do you read the example displayed?
Looks like a named (:session . "org-R") affects global R namespace.
What did "org-R" say here, what might be the purpose?
Assume it should switch it on. Then "org-R" represents a boolean here?
"org-R" is the name of the session. The code blocks illustrate that the value
of x (set in
the first code block) is preserved and can be used in the second (and
subsequent) code
blocks.

Okay, so the :session argument must not be repeated?
i.e. doesn't look like a session, resp. not a named session
#+begin_src R x <- 1 x #+end_src
Once a named session "org-R" is started all non-sessioned source goes there?
Looks like a
broken namespace.
Isn't it the same with all header arguments? when they are set file wide, they
are used for the
source block unless specified otherwise.
Rainer
Hmm, may you point me to the file-wide setting?
Form at stake
(setq org-babel-default-header-args:R '((:session . "org-R")))
seems to put all remaining R-evaluations into a named session "org-R"
Don't see any restriction onto a file resp. buffer. Maybe that's thought
implicit?
Thanks,
Andreas
