R: Plot the Voronoi diagram and Delaunay traingulation

plot.delvor {alphahull} | R Documentation

## 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`).
