"WebFirst, we demonstrate how we can use this new version of glmnet to fit ordinary least squares with the elastic net penalty. We set up some fake data: set.seed (1) x <- matrix ( rnorm (500), ncol = 5) y <- rowSums (x[, 1:2]) + rnorm (100) The function calls below demonstrate how we would fit the model with the old and new family parameter options.
