Data Stream Generator for Bars and Gaussians

Source: R/DSD_BarsAndGaussians.R
DSD_BarsAndGaussians.Rd

A data stream generator which creates the shape of two bars and two Gaussians clusters with different density.

Usage

DSD_BarsAndGaussians(angle = NULL, noise = 0)

Arguments

angle

rotation in degrees. NULL will produce a random rotation.

noise

The amount of noise that should be added to the output.

Value

Returns a DSD_BarsAndGaussians object.
