plot_GMM: Plots Mixture Components from Gaussian Mixture Models

In plotGMM: Tools for Visualizing Gaussian Mixture Models

Description

Generates a plot of data densities with overlaid mixture components from a Gaussian mixture model (GMM)

Usage

plot_GMM(m, k=NULL)

Arguments

m	An object of class mixEM corresponding with the fit GMM
k	The number of components specified in the GMM, m

Details

Uses ggplot2 graphics to plot data densities with overlaid components from mixEM objects, which are GMM's fit using the mixtools package.

Note: Users must enter the same component value, k, in the plot_GMM function, as that which was specified in the original GMM specification (also k in mixtools).
