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...
You have to write code that can be executed in parallel. The parallel package helps, see its documentation.

Thanks! Andrea
