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

   www.computational.unibas.ch/cs/scicomp/software/pardiso
   www.enseeiht.fr/lima/apo/MUMPS/ 

and in these reviews
