Plot clusters on a biplot.

Description

Highlights several groups or clusters on a biplot representation.

Usage

PlotBiplotClusters(A, Groups = ones(c(nrow(A), 1)), TypeClus = "st",
                 ClusterColors = NULL, ClusterNames = NULL, centers =
                 TRUE, ClustConf = 1, Legend = FALSE, LegendPos =
                 "topright", CexClustCenters = 1,  ...)

Arguments

A

Coordinates of the points in the scattergram

Groups

Factor defining the groups to be highlited

TypeClus

Type of representation of the clusters. For the moment just a convex hull but in the future ellipses and stars will be added.

ClusterColors

A vector of colors with as many elements as clusters. If NULL the function slects the raibow colors.

ClusterNames

A vector of names with as many elements as clusters.

centers

Logical variable to control if centres of the clusters are plotted

ClustConf

Percent of points included in the cluster. only the ClusConf percent of the points nearest to the center will be used to calculate the cluster

Legend

Should a legend be plotted

LegendPos

Position of the legend.

CexClustCenters

Size of the cluster centres.

...

Any other graphical parameters

Details

The clusters to plot should be added to the biplot object using the function AddCluster2Biplot.

Value

It takes effects on a plot
