Description
The generated data set consists of 21 attributes with continuous values and a variable showing the 3 classes (33% for each of 3 classes). Each class is generated from a combination of 2 of 3 "base" waves.
Usage

Arguments
n |
number of patterns to create |
Value
Returns an object of class "mlbench.waveform" with components
x |

factor vector of length |
Source
The original C code for the waveform generator was taken from the UCI Repository of Machine Learning Databases (Blake and Merz 1998). The C code was modified to use R's random number generator by Friedrich Leisch, who also wrote the R interface.
