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.
Best,
Ihor
