Provides a convenient stream interface for data sets from the mlbench package.
Value
Returns a DSD_mlbenchData object which is also of class
DSD_Memory.
Details
The DSD_mlbenchData class is designed to be a wrapper class for data
from the mlbench package.
All data is held in memory in either data frame or matrix form. It is served as a stream using the
DSD_Memory class. The stream can be reset to position 1 using reset_stream().
Call DSD_mlbenchData with a missing value for data to get a list of
all available data sets.
