heatDissMat: Plot the heatmap of the dissimilarity matrix

Description

Function to plot the heatmap of the dissimilarity matrix

Usage

heatDissMat(dissimObj, main=NULL, xlab=NULL, ylab=NULL)

Arguments

dissimObj

An object of class dissimObj.

main

The usual plot option, to be passed to the heatmap function.

ylab

The usual plot option, to be passed to the heatmap function.

xlab

The usual plot option, to be passed to the heatmap function.

Value

• Plot of the heatmap of the dissimilary matrix. This functions uses the function 'heatmap' of package 'stats'. Note that this function has not been optimised for large datasets.
