R help - Sep 2007 - glmpath error

Hi,

I am using glampath package for L1 regularized logistic regression. I got
the following error messege.
> model.fit <- glmpath(train.data[,1:20], train.data$RES, family=binomial)
Error in one %*% x : requires numeric matrix/vector arguments

where train.data is a 700X21 matrix and 21st column in response (RES).

Please clarify!!!

Thanks

If it is a matrix, then train.data$RES won't work.  That column 
selection method only works for data frames,
because they are lists, and matrices aren't.
