R: Plot a clique matrix

plotCM

R Documentation

Plot a clique matrix

Description

This function can be used to make an image of a clique matrix (or any other 0-1 matrix). It is basically just the function image, with some pre-defined settings.

Usage

plotCM(cm, col=c("white","black"), at.x=NULL, at.y=NULL, 
       xlab="Observation rectangles", ylab="Maximal intersections", 
       main="", sub="")

Arguments

`cm`	A mxn clique matrix, where m is the number of maximal intersections, and n is the number of observation rectangles. The (i,j)th element is 1 if the ith maximal intersection is contained in the jth observation rectangle, and it is 0 otherwise.
`col`	Colors to be used. The default value is c("white","black").
`at.x`	The points at which tick-marks are to be drawn along the x-axis. The default value is NULL, meaning that tickmark locations are computed automatically. See also the documentation of `axis`.
`at.y`	The points at which tick-marks are to be drawn along the y-axis. The default value is NULL, meaning that tickmark locations are computed automatically. See also the documentation of `axis`.
`xlab`	Label for the x-axis. The default value is "Observation rectangles".
`ylab`	Label for the y-axis. The default value is "Maximal intersections".
`main`	Title of the plot. The default value is empty.
`sub`	Sub-title of the plot. The default value is empty.

Value

No value is returned.

Examples

# Load example data and plot observation rectangles
data(ex)
par(mfrow=c(2,1))
plotRects(ex,main="Rectangles and maximal intersections")

# Perform reduction step and plot maximal intersections (shaded)
res<-reduc(ex, cm=TRUE)
plotRects(res$rects, density=15, border=NA, add=TRUE)

# Plot clique matrix
plotCM(res$cm, main="Clique matrix")
