This is a question about your OS, isn't it?  Does your OS allow you to
run multiple processes on different cores?  Or maybe this is a question
about RStudio.  Does it allow multiple instances to run on the same
computer, so your OS can allocate them to different cores?

If you run your scripts in R (not under RStudio) it's certainly possible
to have multiple R processes running at the same time.  Just do it.
