mlbench Data Stream Generator

A data stream generator class that interfaces data generators found in package mlbench.

Usage

DSD_mlbenchGenerator(method, ...)

Arguments

method

The name of the mlbench data generator. If missing then a list of all available generators is shown and returned.

...

Parameters for the mlbench data generator.

Value

Returns a DSD_mlbenchGenerator object (subclass of DSD_R, DSD)

Details

The DSD_mlbenchGenerator class is designed to be a wrapper class for data created by data generators in the mlbench library.

Call DSD_mlbenchGenerator with missing method to get a list of available methods.
