I'd also add that sparse-matrix functions (which the original poster was
seeking) aren't in the Matrix library in any case (but I'll take this as a
request for them to be included when we do re-introduce the Matrix library to
S-PLUS).
On the other hand, the S+SpatialStats module (available separately) does
include a number of functions for working with sparse matrices since the
neighbour objects are essentially sparse matrices.
