R: Plot a voronoi object

plot.voronoi {interp} | R Documentation

## Plot a voronoi object

### Description

Plots the mosaic `"x"`. Dashed lines are used for outer tiles of the mosaic.

### Usage

    ## S3 method for class 'voronoi'
    plot(x,add=FALSE,
                               xlim=c(min(x$tri$x)-
                                 0.1*diff(range(x$tri$x)),
                                 max(x$tri$x)+
                                 0.1*diff(range(x$tri$x))),
                               ylim=c(min(x$tri$y)-
                                 0.1*diff(range(x$tri$y)),
                                 max(x$tri$y)+
                                 0.1*diff(range(x$tri$y))),
                               all=FALSE,
                               do.points=TRUE,
                               main="Voronoi mosaic",
                               sub=deparse(substitute(x)),
                               isometric=TRUE,
                               ...)

### Arguments

`x` | object of class `"voronoi"`
`add` | logical, if `TRUE`, add to a current plot.
`xlim` | x plot ranges, by default modified to hide dummy points outside of the plot
`ylim` | y plot ranges, by default modified to hide dummy points outside of the plot
`all` | show all (including dummy points in the plot
`do.points` | logical, indicates if points should be plotted.
`main` | plot title
`sub` | plot subtitle
`isometric` | generate an isometric plot (default `TRUE`)
`...` | additional plot parameters

### Value
