plot.Mclust: Plotting method for Mclust model-based clustering

In Japrin/mclust: Gaussian Mixture Modelling for Model-Based Clustering, Classification, and Density Estimation

Description

Plots for model-based clustering results, such as BIC, classification, uncertainty and density.

Usage

## S3 method for class 'Mclust'
plot(x, what = c("BIC", "classification", "uncertainty", "density"), 
     dimens = NULL, xlab = NULL, ylab = NULL, ylim = NULL,
     addEllipses = TRUE, main = FALSE, ...)

Arguments

x	Output from Mclust.
what	A string specifying the type of graph requested. Available choices are: "BIC" plot of BIC values used for choosing the number of clusters. "classification" = a plot showing the clustering. For data in more than two dimensions a pairs plot is produced, followed by a coordinate projection plot using specified dimens. Ellipses corresponding to covariances of mixture components are also drawn if addEllipses = TRUE. "uncertainty" a plot of classification uncertainty. For data in more than two dimensions a coordinate projection plot is drawn using specified dimens. "density" a plot of estimated density. For data in more than two dimensions a matrix of contours for coordinate projection plot is drawn using specified dimens. If not specified, in interactive sessions a menu of choices is proposed.
dimens	A vector of integers specifying the dimensions of the coordinate projections in case of "classification", "uncertainty", or "density" plots.
xlab, ylab	Optional labels for the x-axis and the y-axis.
ylim	Optional limits for the vertical axis of the BIC plot.
addEllipses	A logical indicating whether or not to add ellipses with axes corresponding to the within-cluster covariances in case of "classification" or "uncertainty" plots.
main	A logical or NULL indicating whether or not to add a title to the plot identifying the type of plot drawn.
...	Other graphics parameters.

Details

For more flexibility in plotting, use mclust1Dplot, mclust2Dplot, surfacePlot, coordProj, or randProj.
