Please ask such non-Mac-specific questions on R-help.
For 'arbitrary', no. But there are lots of helpers, including
Runuran, SuppDists and distrSim, which cover lots of univariate
distribtutions. There are lots of multivariate ones implemented too,
often in packages that make use of MCMC. But you cannot even define an
arbitrary distribution in a unified way.

Hi,
I a newbie, I work with a mac.
Is there any package that I can use to generate random samples for arbitrary
distribution, that is , user defined distribution ？
like the simplest
x <- rnorm( something )
and that is a normal distribution.
