Here's a novel idea: Do a google search on "multiprecision computing package R" for an answer.

Read its documentation yourself and unless you have good reason not to, always cc the list (which I have done here).

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.

Thanks! I installed Rmpfr now.
But it does NOT support eigen function ?
x <- array(1:16, dim=c(4,4))
ev <- eigen(x)
********************************
mat <- mpfrArray(1:25, 64, dim = c(5,5))
ev <- eigen(mat)
Error in `dimnames<-`(`*tmp*`, value = NULL) : non-list RHS
********************************

If you want to do a fancy matrix operation, you may need to invent the wheel yourself. Rmpfr only supports limited matrix operations. There may exist some C++ library that can do this job, I will suggest finding a matrix library whose elements are of a template type, then combine it with a multi-precision library so that you can do matrix operations in a very high precision.
