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"-*-
