plot.mat {sma}R Documentation

Red and Green Color Image of Data Matrix

Description

This function produces a red and green color image of a data matrix using an RGB color specification. Larger entries are represented with reds of increasing intensity, and smaller entries are represented with greens of increasing intensity.

Usage

plot.mat(x, nrgcols=50, rlabels=FALSE, clabels=FALSE, rcols=1, ccols=1, title="",...)

Arguments

x a matrix of numbers.
nrgcols the number of colors (>= 1) to be used in the red and green palette.
rlabels vector of character strings to be placed at the row tickpoints, labels for the rows of X.
clabels vector of character strings to be placed at the column tickpoints, labels for the columns of X.
rcols colors to be used for the labels of the rows of X. rcols can have either length 1, in which case all the labels are displayed using the same color, or the same length as rlabels, in which case a color is specified for the label of each row of X.
ccols colors to be used for the labels of the columns of X. ccols can have either length 1, in which case all the labels are displayed using the same color, or the same length as clabels, in which case a color is specified for the label of each column of X.
title character string, overall title for the plot.
... graphical parameters may also be supplied as arguments to the function (see par). E.g. zlim=c(-3,3)
