+@code{glmnet} and @code{caret} packages.  With glmnet this includes
+cross-validation of elastic net alpha parameter.  A number of feature
+selection filter functions (t-test, Wilcoxon test, ANOVA, Pearson/Spearman
+correlation, random forest, ReliefF) for feature selection are provided and
+can be embedded within the outer loop of the nested CV.  Nested CV can be also
+be performed with the @code{caret} package giving access to the large number
+of prediction methods available in @code{caret}.")
