sparse matrix tools
Dear R-Help list:
I'm using the Matrix library to operate on 600 X ~5000 element
unsymmetrical sparse arrays. So far, so good, but if I find I need more
speed or functionality, how hard would it be to utilize other sparse
matrix toolsets from within R, say MUMPS, PARDISO or UMFPACK, that do
not have explicit R interfaces? More information on these is available
here

Developmental version of Matrix package for R-1.9.0
...the packages
that will appear in R-1.9.0.
This version marks a major redesign of the Matrix package to use S4
classes and methods and to incorporate sparse matrix manipulations
using routines from TAUCS (http://www.tau.ac.il/~stoledo/taucs/),
Metis (http://www-users.cs.umn.edu/~karypis/metis/) and UMFPACK
(http://www.cise.ufl.edu/research/sparse/umfpack).
Although this package is very much a work in progress and the
documentation is, shall we say, sketchy, there are two vignettes
included with the package. One of these illustrates the performance
of different ways of performing least squares calcu...
