[luau] Mandrake rules again

[Ray Strode]

At the CompUSA event, a nice Danish man (I'm sorry, I can't remember his 
name), told me about
a program called R <http://www.r-project.org/>.  It's supposed to be a 
like S-plus, so i think it's more for
statistics/probabilities/finite math than calculus, but i thought i'd 
mention it.

Of course for intregration there is always the integrator,

(basically mathematica hooked up to a web interface)
