      Description

      RandomForest uses BaggedPoint to simulate bootstrapped samples of the data. The expected size of each sample is the same as the original data (sampling rate = 1.0), and sampling is done with replacement. Adding support for other sampling rates and for sampling without replacement would be useful.
