About the multiprecision computing package in R
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.

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

Dear all
I need a multiprecision computing package in R, if anyone in the list
knows, please let me known...
Many thanks
