plot_gmm {plotmm}

Plots Mixture Components from 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

Original function from the plotGMM package. Retained here for bridging between the packages. We recommend using instead the updated plot_mm function.

Note: plot_gmm requires a mixtools object to be supplied. 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).
