plot.delvor: Plot the Voronoi diagram and Delaunay traingulation

In alphahull: Generalization of the Convex Hull of a Sample of Points in the Plane

Plot the Voronoi diagram and Delaunay traingulation

Description

This function returns a plot of the Voronoi diagram and Delaunay traingulation.

Usage

## S3 method for class 'delvor'
plot(x, add = FALSE, wlines = c("both", "del", "vor"),
	wpoints = TRUE, number = FALSE, col = NULL, 
	xlim = NULL, ylim = NULL, ...)

Arguments

x	An object of class "delvor" as constructed by the function delvor.
add	Logical, if TRUE add to a current plot.
wlines	"Which lines?". I.e. should the Delaunay triangulation be plotted (wlines='del'), should the Voronoi diagram be plotted (wlines='vor'), or should both be plotted (wlines='both', the default)?
wpoints	Logical, indicates if sample points should be plotted.
number	Logical, defaulting to FALSE; if TRUE then the points plotted will be labelled with their index numbers.
col	The colour numbers for plotting the data points, Delaunay triangulation, Voronoi diagram, and the point numbers, in that order; defaults to c(1,1,1,1). If fewer than four numbers are given, they are recycled. (If more than four numbers are given, the redundant ones are ignored.)
xlim	The limits on the x-axis.
ylim	The limits on the y-axis.
...	Arguments to be passed to methods, such as graphical parameters (see par).
