Sparse Matrix- what's the best way to get this into Splus?

["Steve Su" <s.su@qut.edu.au>]

Dear All,

Thank you James Holtman, Andy Liew and Patrick Burns who replied to my
questions on creating large zero matrices. 

The general response appears that I should code this into a sparse
matrix. 

I had a look at the archives in R and Splus and it appears that the 
library(Matrix) may be useful, however this response is related to R
rather than Splus? I also noticed that the library Matrix is not in
Splus6.

The other reference is at

However I am not sure if these functions are well supported or has there
been any improvements made on those functions? 

Andy Liew also suggested that there is a package in R and it appears
there is in fact one, is it possible to load this into Splus? 

Thanks for your attention and assistance.

Steve.
