Description

Provides a convenient stream interface for data sets from the mlbench package.

Usage

DSD_mlbenchData(data = NULL, loop = FALSE, random = FALSE, scale = FALSE)

Value

Returns a DSD_mlbenchData object which is also of class DSD_Memory.

Arguments

data

The name of the dataset from mlbench. If missing then a list of all available data sets is shown and returned.

loop

logical; loop or not to loop over the data frame.

random

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.
