plot.mat {sma} | R Documentation |
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.
plot.mat(x, nrgcols=50, rlabels=FALSE, clabels=FALSE, rcols=1, ccols=1, title="",...)
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) |
