gl.plot.heatmap: Represents a distance matrix as a heatmap

Description

The script plots a heat map to represent the distances in the distance or dissimilarity matrix. This function is a wrapper for heatmap.2 (package gplots).

Usage

gl.plot.heatmap(D, palette.divergent = gl.colors("div"), verbose = NULL, ...)

Value

returns no value (i.e. NULL)

Arguments

D

Name of the distance matrix or class fd object [required].

palette.divergent

A divergent palette for the distance values [default gl.colors("div")].

verbose

Verbosity: 0, silent or fatal errors; 1, begin and end; 2, progress log; 3, progress and results summary; 5, full report [default 2 or as specified using gl.set.verbosity]
