plot.mat: Red and Green Color Image of Data Matrix
In gnyamundanda/sma: Statistical Microarray Analysis

Description Usage Arguments Author(s) See Also Examples

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.

1	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)`
