%description
Provides several functions to simplify using the 'glmnet' package:
converting data frames into matrices ready for 'glmnet'; b) imputing
missing variables multiple times; c) fitting and applying prediction
models straightforwardly; d) assigning observations to folds in a balanced
way; e) cross-validate the models; f) selecting the most representative
model across imputations and folds; and g) getting the relevance of the
model regressors; as described in several publications: Solanes et al.
