[Blindmath] Two questions for those who use R

[sarah.jevnikar at utoronto.ca]

Hi,
I've heard that "batch" mode or something that sounds similar can work  
too. Could someone please explain this to me? I am trying to make it  
work with Mathematica as well (through command line mode) with little  
success.

Thank you,
Sarah
