Can't run glmnet() R package : “ could not find function ”lengths“ ”

Question

I'm using glmnet R package. And before today I had no problems using it. I installed caret two days ago, I had some troubles to install it but I succeeded to do some by re-installing some packages like.

Here is the error message I get :

Error in .fixupDimnames(.Object@Dimnames) : 
could not find function "lengths"

I'm using an old version of R, that I can't update right now.

The error is obtained after calling :

gg <- glmnet(x=data, y=Y.train, family="binomial", alpha=0, lambda=1)

Y.train is factor, and data a matrix of dummies. But I think that the issue is not a matter of data. But it is more likely something linked with a package or something like this that I'm missing. If anybody has a clue, it would be great.

I reinstall Matrix_1.1-1.tar.gz, and it worked. So, you can try to change your Matrix package.
