plotCategorial {clusterSim}R Documentation

Plot categorial data on a scatterplot matrix

Description

Plot categorial data on a scatterplot matrix (optionally with clusters)

Usage

plotCategorial(x, pairsofVar=NULL, cl=NULL, clColors=NULL,...)

Arguments

x data matrix (rows correspond to observations and columns correspond to variables)
pairsofVar pairs of variables - all variables (pairsofVar=NULL) or selected variables, e.g. pairsofVar=c(1,3,4)
cl cluster membership vector
clColors The colors of clusters. The colors are given arbitrary (clColors=TRUE) or by hand, e.g. clColors=c("red","blue","green"). The number of colors equals the number of clusters
... Arguments to be passed to methods, such as graphical parameters (see par).
