Hi
Attached please find seven patches for review to implement the storing
of org variables in their own environment and to make the org-issued R
code look nicer in the R session.
Rainer,
I have suggestions and a concern.

That is effectively what I am doing as well, only that I am not using a

OK. I did not study your patches closely enough. Sorry.
I also suggest that you introduce a customization variable to
allow a user to turn off the functionality you have created.
I don't think this is necessary as the behavior for the user does not
change at all, only that it becomes safer to use org variables in R (see
above).
All you have to do is add this:
(defvar org-babel-R-assign-elisp-function 'org-babel-R-assign-elisp
"Name or definition of function to handle `:var name=value'
header args."
)
and change one line in org-babel-variable-assignments:R from
(org-babel-R-assign-elisp
to
(funcall org-babel-R-assign-elisp-function
and the user can provide her own elisp assignment function.
This gives users who want special behavior like creating something
other than a data.frame the option of providing their own function.
Best,
Chuck
