It depends on source block language.  For Python, there is :python
header arg where you can specify python command to be used.  I am not
sure about R

More generally, you can advice org-babel-execute-src-block and wrap it
into something like with-environment-variables macro (available in
newest Emacs).

Or you can write a bash source block, set envitonment there as usual,
and invoke your Python/R script using noweb.

Hope it helps.
