WebJan 10, 2024 · However when you specify x and y it will not work because glmnet takes the x in the form of a model matrix, When you supply the formula to caret it will take care of model.matrix creation but if you just specify the x and y then it will assume x is a model.matrix and will pass it to glmnet. For instance this works: x <- …
