mclust (version 4.1)

plot.Mclust: Plot Model-Based Clustering Results

Description

Plot model-based clustering results: BIC, classification, uncertainty and (for univariate and bivariate data) density.

Usage

## S3 method for class 'Mclust':
plot(x, what = c("BIC", "classification", "uncertainty", "density"), 
     dimens = NULL, xlab = NULL, ylim = NULL,
     addEllipses = TRUE, identify = TRUE, 
     legendArgs = list(x = "bottomright", ncol = 2, cex = 1), 
     ...)

Arguments

x

Output from Mclust.

what

The type of graph requested: [object Object],[object Object],[object Object],[object Object] By default, all the above graphs are produced. See the description below.

dimens

A vector of length one or two giving the integer dimensions of the desired coordinate projections for multivariate data in case of "classification" or "uncertainty" plots.

xlab

Optional label for the horizontal axis of the BIC plot.

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 if what = "classification".

identify

A logical indicating whether or not to add a title to the plot identifying the dimensions used.

legendArgs

Arguments to pass to the legend function. Set to NULL for no legend.

...

Other graphics parameters.

Value

• Model-based clustering plots: [object Object],[object Object],[object Object],[object Object]
