\description{
Learners like \code{randomForest} produce out-of-bag predictions.
\code{getOOBPreds} extracts this information from trained models and builds a
prediction object as provided by predict (with prediction time set to NA).
In the classification case:
What is stored exactly in the (\link{Prediction}) object depends
on the \code{predict.type} setting of the \link{Learner}.
You can call \code{listLearners(properties = "oobpreds")} to get a list of learners
which provide this.
