> Looking for a recommended package that handles prime number computations.
I'm not sure whether this would be helpful to you, but Sage (http://www.sagemath.org) has excellent number theory support and several ways to interface with R (which is included in the distribution of Sage). I use it myself to access several R packages I need to do analysis on data I produce in Sage/Python, and then send the data back to Sage for further processing. Of course, this is not an R package, so depending on how much you need such things from within R itself it may or may not help you out.
