plot.tango: Plots an object of class 'tango'.

In smerc: Statistical Methods for Regional Counts

Plots an object of class tango.

Description

Plots results of tango.test. If Monte Carlo simulation was not used to produce x, then a a density plot of the (approximate) null distribution of tstat.chisq is produced, along with a vertical line for the observed tstat. If a Monte Carlo test was used to produce x, then a scatterplot of the gof.sim versus sa.sim is compared to the observed values gof and sa, respectively.

Usage

## S3 method for class 'tango'
plot(x, ..., obs.list = list(pch = 20), sim.list = list(pch = 2))

Arguments

x	An object of class tango to be plotted.
...	Additional graphical parameters passed to plot function.
obs.list	A list containing arguments for the points function, which is used to plot the gof and sa components, when appropriate.
sim.list	A list containing arguments for the points function, which is used to plot the gof.sim and sa.sim components, when appropriate.

Examples

data(nydf)
coords <- as.matrix(nydf[, c("x", "y")])
w <- dweights(coords, kappa = 1)
x1 <- tango.test(nydf$cases, nydf$pop, w)
plot(x1)
x2 <- tango.test(nydf$cases, nydf$pop, w, nsim = 49)
plot(x2)
