Recently, Friedman, Hastie and Tibshirani (2008) have developped and algorithm to compute the entire solution path of the Lasso for an arbitrary generalized linear model, implemented in the package \code{glmnet}. The method can be used for variable selection alone, s. \code{\link{GeneSelection}} } \section{Methods}{ \describe{ \item{X = "matrix", y = "numeric", f = "missing"}{signature 1} \item{X = "matrix", y = "factor", f = "missing"}{signature 2} \item{X = "data.frame", y = "missing", f = "formula"}{signature 3} \item{X = "ExpressionSet", y = "character", f = "missing"}{signature 4} } For references, further argument and output information, consult \code{\link{LassoCMA}}. } \keyword{multivariate}
