[R] R code for performance

[v.demartino2@virgilio.it]

At office I'm cautiously introducing R to be used as the basic statistical
program, getting rid of licensed stuff or reducing the amount of it.
The aim of R would be to run generic statistical programs built & "consumed"
when needed and some static procedure dealing with time-series.
Now, we have substantially 3 OS platforms, win xp, linux and freebsd 5.4,
on similar PCs (pentium 4, 2-2.5 GHz). I have been asked by the boss to
test the "average" performance (in term of speed and memory use) of R on
each of this platform to stick with one of them on a couple of PCs.

Could you please suggest an R source code (apart from the "static procedure"
I will obviously test) to be run on the three platforms to test performance?

If there is nothing of the kind, any suggestion?

Ciao
