Plotting of a Matrix

Description

myImagePlot: R implementation of myImagePlot.

Usage


myImagePlot(x,xLabels=NULL, yLabels=NULL, zlim=NULL, title=NULL)

Arguments

x the matrix.
xLabels vector of strings to label the columns (default "colnames(x)").
yLabels vector of strings to label the rows (default "rownames(x)").
zlim vector containing a low and high value to use for the color scale.
title title of the plot.

Details

Plotting a table of numbers as an image using R.

The color scale is based on the highest and lowest values in the matrix.
