\title{Plot Confidence Ellipses for FLXMCmvnorm Results}
\description{
Plot 50\% and 95\% confidence ellipses for mixtures of Gaussians fitted using
\code{\link{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{
\item{object}{An object of class \code{flexmix} with a fitted
\code{FLXMCmvnorm} model.}
\item{data}{The response variable in a data frame or as a matrix.}
\item{which}{Index numbers of dimensions of (projected) input space
to plot.}
\item{model}{The model (for a multivariate response) that shall be
plotted.}
\item{project}{Projection object, currently only the result of
\code{\link[stats]{prcomp}} is supported.}
\item{points}{Logical, shall data points be plotted?}
\item{eqscale}{Logical, plot using \code{\link[MASS]{eqscplot}}?}
\item{number}{Logical, plot number labels at cluster centers?}
\item{cex, numcol}{Size and color of number labels.}
\item{pch, col, \dots}{Graphical parameters.}
