plot.mona {cluster}R Documentation

Banner of Monothetic Divisive Hierarchical Clusterings

Description

Creates the banner of a mona object.

Usage

plot.mona(x, main = paste("Banner of ", deparse(attr(x, "Call"))),
          col = 2, axes = TRUE, adj = 0,
          nmax.lab = 35, max.strlen = 5, ...)

Arguments

x an object of class "mona", typically created by mona(.).
main main title for the plot, with a convenient default. See documentation for main in plot.default.
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.
axes logical, indicating if (labeled) axes should be drawn.
col,adj,... graphical parameters (see par) may also be supplied as arguments to this function.

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).

Side Effects

A banner is plotted on the current graphics device.

Note

In the banner plot, observation labels are only printed when the number of observations is limited less than nmax.lab (35, by default), for readability. Moreover, observation labels are truncated to maximally max.strlen (5) characters.
