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`).

`delvor`.

### Examples

```## Not run:
# Random sample in the unit square
x <- matrix(runif(100), nc = 2)
# Delaunay triangulation and Voronoi diagram
delvor.obj <- delvor(x)
# Plot Voronoi diagram and Delaunay triangulation
plot(delvor.obj)

## End(Not run)
