glmnet_1.2 has been uploaded to CRAN.

This is a major upgrade, with the following additional features:

Here is the description of the package.

glmnet is a package that fits the regularization path for linear, two- and multi-class logistic regression models, poisson regression and the Cox model, with "elastic net" regularization (tunable mixture of L1 and L2 penalties). glmnet uses pathwise coordinate descent, and is very fast.

Some of the features of glmnet:

Examples of glmnet speed trials:
Newsgroup data: N=11,000, p= 0.75 Million, two class logistic. 100 values along lasso path. Time = 2mins 14 Class cancer data: N=144, p=16K, 14 class multinomial, 100 values along lasso path. Time = 30secs
