Yes!  Indeed!  And, Thanks!  

And... I don't even need to remember to eval the setq statement if I include in 
my org the following works everytime

# Local Variables:
# org-babel-R-command: "R-3.0.1 --slave --no-save"
# End:

Or put it as first line in the file:

# -*- org-babel-R-command: "R-3.0.1 --slave --no-save"-*-

 Indeed, John,  that is the variable I would like to have respected when I

 (setq-local inferior-R-program-name R-3.0.1)


 But, alas it is not.

 Any other takers?

 Thanks!

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.

[O] HowTo? have R :sessions in org mode invoke a specific R

[Cook, Malcolm]

I wish to lock an org buffer to a particular installation of R so that all code 
blocks use it.

I found that I could not, for instance, write `:session R-3.0.1`.

Is there some best way for me to accomplish this?

Perhaps some way of setting inferior-R-program-name to a buffer local value?

Thanks!

I'm no good at in-buffer variables, but this one looks of interest:
org-babel-R-command

Mine on linux is just set to `R --slave --no-save`, but on Windows, I
have to set the full path, so there's no reason you couldn't do the
same (just that I simply use setq() and you'd be doing it in-buffer).


Hope that helps,
John


 Thanks!
