[R] Latin Hypercube Sampling in R?

[Dan Loughlin]

Hi,
I am interested in using R to perform Monte Carlo simulation using MC
sampling, Latin Hypercube Sampling (LHS), and importance sampling. While
I'm sure I can code R to do LHS, I would be surprised if others had not
done so. Is there R code publically available for this purpose? (I have
searched CRAN and the WWW extensively with no luck). Thanks in
advance.
