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". > library(Matrix) Loading required package: lattice Attaching package: 'Matrix' The following object(s) are masked from 'package:base': det > sessionInfo() R version 2.13.0 (2011-04-13) Platform: x86_64-pc-linux-gnu (64-bit) locale: [1] LC_CTYPE=en_US.UTF-8 LC_NUMERIC=C [3] LC_TIME=en_US.UTF-8 LC_COLLATE=en_US.UTF-8 [5] LC_MONETARY=C LC_MESSAGES=en_US.UTF-8 [7] LC_PAPER=en_US.UTF-8 LC_NAME=C [9] LC_ADDRESS=C LC_TELEPHONE=C [11] LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=C attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] Matrix_0.9996875-0 lattice_0.19-17 loaded via a namespace (and not attached): [1] grid_2.13.0 > example(spMatrix) ... output omitted > A 10 x 20 sparse Matrix of class "dgTMatrix" [1,] . 7 . . . . . . . . . . . . . . . . . .
