plot.mona: Banner of Monothetic Divisive Hierarchical Clusterings

Description

Creates the banner of a mona object.

Usage

# S3 method for mona
plot(x, main = paste("Banner of ", deparse(x$call)),
          sub = NULL, xlab = "Separation step",
	  col = c(2,0), axes = TRUE, adj = 0,
          nmax.lab = 35, max.strlen = 5, …)

Arguments

x

an object of class "mona", typically created by mona(.).

main,sub

main and sub titles for the plot, with convenient defaults. See documentation in plot.default.

xlab

x axis label, see title.

col,adj

graphical parameters passed to bannerplot().

axes

logical, indicating if (labeled) axes should be drawn.

nmax.lab

integer indicating the number of labels which is considered too large for labeling.

max.strlen

positive integer giving the length to which strings are truncated in labeling.

…

further graphical arguments are passed to bannerplot() and text.

Side Effects

A banner is plotted on the current graphics device.

Details

Plots the separation step at which clusters are splitted. The observations are given in the order found by the mona algorithm, the numbers in the step vector are represented as bars between the observations.

When a long bar is drawn between two observations, those observations have the same value for each variable. See chapter 7 of Kaufman and Rousseeuw (1990).
