Plot Model-Based Clustering Results

Description

Plot model-based clustering results: BIC, classification, uncertainty and (for one- and two-dimensional data) density.

Usage

plot.Mclust(x, data, dimens = c(1, 2), scale = FALSE, ...)

Arguments

x Output from Mclust.
data The data used to produce x.
dimens An integer vector of length two specifying the dimensions for coordinate projections if the data is more than two-dimensional. The default is c(1,2) (the first two dimesions).
scale A logical variable indicating whether or not the two chosen dimensions should be plotted on the same scale, and thus preserve the shape of the distribution. Default: scale=FALSE
... Further arguments to the lower level plotting functions.

Value

Plots selected via a menu including the following options: BIC values used for choosing the number of clusters For data in more than two dimensions, a pairs plot of the showing the classification, coordinate projections of the data, showing location of the mixture components, classification, and/or uncertainty. For one- and two- dimensional data, plots showing location of the mixture components, classification, uncertainty, and or density.
