fwdmvEllipsePlot {Rfwdmv}R Documentation

Ellipses Plot of an fwdmv Object

Description

A pairs like plot. The subsets within each group are represented by concentric ellipses drawn to contours of the bivariate normal distribution. Units in the tentative groups that are not in the subsets are plotted as points and the indices of the unassigned units are plotted as text.

Usage

fwdmvEllipsePlot(x, subset.size, plot.diagonal = TRUE)

Arguments

x an fwdmv object.
subset.size an integer specifying (by its size) which subset to use to draw the ellipses.
plot.diagonal a logical value. If TRUE then univariate boxplots are drawn along the main diagonal.

Value

an empty list is invisibly returned.

Note

For initial fwdmv objects the unassigned units are plotted as points.
