Many years ago, I required sparse matrix algebra capacities in
R for my research. The packages available at that time where not
necessarily satisfying for my purpose. Hence, I started writing my own
functions, somewhat inspired by the package SparseM
.
Over the years, I decided to write an R package, called spam
.
In mean time, we have tree significant sparse matrix packages posted
on CRAN. I believe that all three have their own niche of users.
I believe that spam
is stable, useful but definitely not fully
matured. I appreciate all comments and remarks.
There is no need to maintain here a complete list of changes. Older
versions are available on CRAN (>0.11), each coming with a proper
history file.
