Please provide an example. It will also help to include the output of
sessionInfo()
so we can determine exactly which version of R and the Matrix package
you are using on what platform. Also try
> find("t")
[1] "package:Matrix" "package:base"
to see which version of "t" is the first on the search path.
It seems to still be working for me, but "outside the package".
