oclust (version 1.0.0)

plot.oclust: Plots results of the ‘oclust’ algorithm.

Description

Plots results of the ‘oclust’ algorithm.

Usage

# S3 method for oclust
plot(
  x,
  what = c("classification", "KL", "pval"),
  dimens = NULL,
  xlab = NULL,
  ylab = NULL,
  ylim = NULL,
  addEllipses = TRUE,
  ...
)

Arguments

x

An ‘oclust’ class object obtained by using oclust

what

A string specifying the type of graph. The options are: "classification" a plot of the classifications for the optimal solution. For data with p>2, if more than two "dimens" are specified, a pairs plot is produced. If two "dimens" are specified, a coordinate projection plot is produced with the specified "dimens". Ellipses corresponding to covariances of mixture components are also drawn if "addEllipses = TRUE". "KL" a plot of Kullback-Leibler divergence for each number of outliers. "pval" a plot of approximate p-value for each number of outliers.

dimens

a vector specifying the dimensions of the coordinate projections

xlab, ylab

optional argument specifying axis labels for the classsification plot

ylim

optional limits of the y axis of the BIC and KL plots

addEllipses

logical indicating whether to include ellipses corresponding to the covariances of the mixture components
