plotmm (version 0.1.2)

plot_mm: Tidy Visualization of Mixture Models

Description

Generates a ggplot of data densities with overlaid mixture components from fit mixture models.

Usage

plot_mm(m, k = NULL, data = NULL)

Arguments

m

A mixture model object

k

Optional. The number of components specified in the mixture model, m

data

Name of data object required only for EMCluster objects

Details

This is the core function in the package, returning a ggplot object for a fit mixture model. The plot includes the data density with overlaid mixture components.
