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. NickOkay, 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_srcOnce 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
