plotColorRange: Plot color scale.

In clusterGenomics: Identifying clusters in genomics data by recursive partitioning

Description

Plots the color scale used by the method plotHeatmap.

Usage

plotColorRange(colrange)

Arguments

colrange

output from call to plotHeatmap.

Details

This method is designed to be used in conjunction with plotHeatmap and plots the color range used in a call to the latter method. It does not create a new graphics device if one is already open, so it is typically preceded by a call to windows() or a similar method.

Examples

## Create a dummy data set with 50 rows and 100 columns
X = matrix(rnorm(50*100), 50)

## Create a screen with 3 x 3 virtual panels and use the last two rows for the 
## heatmap
layout(matrix(c(2,3,3,1,1,1,1,1,1),3,3,byrow=TRUE))
par(mar=c(2,2,2,2))

## Plot heatmap and then the color range above the heatmap
crange = plotHeatmap(X, c(0,0))  # c(0,0) specifies no margin around heatmap
plotColorRange(crange)
