plot.cugtest: Plotting for cugtest Objects

Description

Plots the distribution of a CUG test statistic.

Usage

# S3 method for cugtest
plot(x, mode="density", ...)

Arguments

x

A cugtest object

mode

``density'' for kernel density estimation, ``hist'' for histogram

Additional arguments to plot

Value

None

Details

In addition to the quantiles associated with a CUG test, it is often useful to examine the form of the distribution of the test statistic. plot.cugtest facilitates this.

Examples

Run this code
# NOT RUN {
#Draw two random graphs, with different tie probabilities
dat<-rgraph(20,2,tprob=c(0.2,0.8))

#Is their correlation higher than would be expected, conditioning 
#only on size?
cug<-cugtest(dat,gcor,cmode="order")
summary(cug)
plot(cug)

#Now, let's try conditioning on density as well.
cug<-cugtest(dat,gcor)
plot(cug)
# }
