Hello:

I have somewhat of a generic question.  How do you use multiple CPU/core
processors in R?  For those familiar with Mplus software, I'm looking for
something analogous to PROCESSORS command in Mplus to speed up processing.
 I searched previous helps/googled it and see that there is a multicore and
parallel package, but I am not understanding how to use these packages.  Is
there a straightforward way to tell R to use more than one processor?

In my search, I found this:
Sys.setenv(MC_CORES=12)
but am unsure what it does...

Thanks!
Andrea
