Hi Achim, thanks for the recommendation. As I said before, see my
previous patch as a proof-of-concept and not as something that I think
should be applied. I am fully aware of the potential consequences.

Using strict is complicated by use of variables from org tables and the
way that the code in R is executed. It would require the variable @r and
each of the created variables from tables to be defined as my. I know I
can change the behaviour of org-babel-variable-assignment, but perhaps
simply adding "my" to any variable created in org would be a good thing
to do. I don't think it would harm, anyways.

thanks, this i a great suggestion that I didn't know about.
