in last few months i've worked on number of projects i've used glmnet package fit elastic net models. it's great, interface rather bare-bones compared r modelling functions. in particular, rather specifying formula , data frame, have give response vector , predictor matrix. lose out on many quality-of-life things regular interface provides, eg sensible (?) treatment of factors, missing values, putting variables correct order, etc. so i've ended writing own code recreate formula/data frame interface. due client confidentiality issues, i've ended leaving code behind , having write again next project. figured might bite bullet , create actual package this. however, couple of questions before so: are there issues complicate using formula/data frame interface elastic net models?
