[R] Re : Matrix package loading problem "Error : object ‘kronecker’ is not exported by 'namespace:methods'"

[Pascal Oettli]

Hello,

Did you upgrade your R version from a previous one to the current one? If yes, probably you should use:

> update.packages(checkBuilt=TRUE).

Best Regards,
Pascal

Objet : [R] Matrix package loading problem "Error : object ‘kronecker’ is not exported by 'namespace:methods'"

Hi R users all ,

I have a clean install of R-2.15.0 in a win32 machine and a problem loading
Matrix 1.0-6 that looks like this:

> library(Matrix)
Loading required package: lattice
Error : object ‘kronecker’ is not exported by 'namespace:methods'
Error: package/namespace load failed for ‘Matrix’
>

I understand that kronecker() now has an S4 generic in package methods. Is
that a clue? I don't know what I can do with this.

Here's my sessionInfo() and the library(Matrix)  error again:
