[R] running R UNIX in a mac computer

[Tiago R Magalhaes]

Hi to you all

My question is:

there is a package written in UNIX for which there is no Mac version.

I would like to know if it's possible to install the R UNIX version on the
MacOSX and run that UNIX package on my Mac (through this UNIX R Vresion on
a Mac)

I have seen a porfile for r version 1.8.1 on darwin:
http://r.darwinports.com/
is that it?

aother question related to that
if it's possible to use UNIX R in Mac, does anyone know how fast or how
slow that is?

thanks for any help!
