Indeed. It's not even yet in the *development* version of Matrix
on R-forge, see
packageDescription("Matrix")[["URL"]]
but it probably will be "real soon now".
The problem with that R-forge version (1.3-0) of Matrix is that
half a dozen CRAN packages at least need to be slightly fixed
before that Matrix version becomes default on CRAN, as these
packages make assumptions about unspecified behavior of some
Matrix functions, notably Matrix::Matrix() which in that next version
of Matrix will produce "diagonalMatrix" instead of
"CsparseMatrix" objects in more cases.... a good thing, but not
what those packages have assumed...
@Spencer: Are you actively using 'giveCsparse = ..' somewhere
in your code?
If not, why would you be interested in the details of the changes
(which would be entirely invisible to you as user) ?
