Getting faster matrix operations in more recent R versions

[ChristineStawitz-NOAA]

Hi all,

@Andrea-Havron-NOAA and I found this StackOverflow thread which works on my PC to get the faster matrix libraries working in a more recent version of R: https://stackoverflow.com/questions/38090206/linking-intels-math-kernel-library-mkl-to-r-on-windows

This requires admin privileges unless you have a portable R install (e.g. under Documents or somewhere other than Program Files) in which case you might be able to get it to work.

Instead of editing the Rprofile.site file as described in step 6, I just ran options(repos = c(CRAN="@CRAN@")) in my R session once I followed the steps and reopened R.
