plotEll {flexmix}

Plot Confidence Ellipses for FLXMCmvnorm Results

Description

Plot 50% and 95% confidence ellipses for mixtures of Gaussians fitted using FLXMCmvnorm.

Usage

plotEll(object, data, which = 1:2, model = 1, project = NULL, points = TRUE,
        eqscale = TRUE, col = NULL, number = TRUE, cex = 1.5, numcol = "black", 
        pch = NULL, ...)

Arguments

object

An object of class flexmix with a fitted FLXMCmvnorm model.

data

The response variable in a data frame or as a matrix.

which

Index numbers of dimensions of (projected) input space to plot.

model

The model (for a multivariate response) that shall be plotted.

project

Projection object, currently only the result of prcomp is supported.

points

Logical, shall data points be plotted?

eqscale

Logical, plot using eqscplot?

number

Logical, plot number labels at cluster centers?

cex, numcol

Size and color of number labels.

pch, col, ...
