varImp.caretStack

This is a function to extract variable importance from a caretStack.

Functions for creating ensembles of caret models: caretList()
and caretStack(). caretList() is a convenience function for fitting multiple
caret::train() models to the same dataset. caretStack() will make linear or
non-linear combinations of these models, using a caret::train() model as a
meta-model.
