9 years ago Whoops. I just submitted a separate issue for this very thing -- I entirely agree.
We might want to make caretStack or caretEnsemble store anything we can take out of all the models that is needed, but not needed to be repeated.

Goes through the models are removes data that isn't needed, e.g. resamples, out-of-sample predictions, the original dataset, and anything else we can think of.
After making a caretEnsemble or caretStack, we'd run clean.caretList to shrink the final models as much as possible.
