Markov Decision Process package?

Hello all:

I posted a similar question in the SAS forum (asking if SAS had the capabilities of doing some type of Markov Decision Process). Since I am not convinced that it does (there is a PROC MCMC but I do not think it is technically for the Markov Decision Process, just the Markov Chain) I thought I would see if there is any type of package in R that can run a Markov Decision Process?

Any thoughts?
Is there an R package that performs a Markov Decision Process? SAS has PROC MCMC which does Markov Decision Chains but a Markov Decision Process involves rewards and more than just 1 action and outcome, so it's slightly more complicated than just a Markov Decision Chain. That's why I'm curious if R has any type of Markov Decision Process capabilities?
