Dear All,

After upgrading to R-2.4.0-dapper2 (my system is ubuntu 6.06 LTS), I often
met problems when loading some packages like Matrix.

Here is the details:

> library(Matrix)
Error in loadNamespace(package, c(which.lib.loc, lib.loc), keep.source =
keep.source) :
        in 'Matrix' methods specified for export, but none defined: Arith,
Math, Math2, +, %*%, Schur, as.matrix, chol, colMeans, colSums, coerce,
crossprod, determinant, diag, dim, dimnames, dimnames<-, expand, expm,
kronecker, image, norm, rcond, rowMeans, rowSums, show, solve, t, tcrossprod
Error: package/namespace load failed for 'Matrix'

Here is my system:

> sessionInfo()
R version 2.4.0 (2006-10-03)
i486-pc-linux-gnu

locale:
LC_CTYPE=en_US.UTF-8;LC_NUMERIC=C;LC_TIME=en_US.UTF-8;LC_COLLATE=en_US.UTF-8;LC_MONETARY=en_US.UTF-8;LC_MESSAGES=en_US.UTF-8;LC_PAPER=en_US.UTF-8;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=en_US.UTF-8;LC_IDENTIFICATION=C

attached base packages:
[1] "methods"   "stats"     "graphics"  "grDevices" "utils"     "datasets"
[7] "base"


I have re-installed the packages after the upgrade. Anyone experienced the
similar problems?

Thanks for your help,

FD
