hi: you also may want to look at the admit package. it does metropolis
hastings using a weighted mixture of t-distributions so you just need to
write a function for the likelihood you're trying to get the parameters for.
I don't know about it's speed or efficiency for large data sets but
you could try it and see what happens. I've used it and it was fine but the
data set was
not large. good luck.
