I think you got it backwards: if you are trying to use org-babel to
evaluate an R code block, then the variable you should set is
org-babel-R-command as John indicated. Setting inferior-R-program-name
to something does not tell anything to org-babel. To use your term,
org-babel does not respect inferior-R-program-name; the only thing it
knows is org-babel-R-command. Only ESS respects inferior-R-program-name,
but you are not using ESS here. So have you tried

 (setq-local org-babel-R-command "R-3.0.1 --slave --no-save")

in your org-mode buffer where you are evaluating your R code?
The options are guesses based on the current setting. Untested since
I know virtually nothing about R.
