[R] About the multiprecision computing package in R

[J C Nash]

Rmpfr does "support" matrix algebra, but I have been trying for some
time to determine if it computes "double" precision (i.e., double the
set level of precision) inner products. I suspect that it does NOT,
which is unfortunate. However, I would be happy to be wrong about
this.
