# plot.voronoi: Plot a voronoi object In tripack: Triangulation of Irregularly Spaced Data

## Description

Plots the mosaic `"x"`.

Dashed lines are used for outer tiles of the mosaic.

## Usage

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16``` ```## 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=FALSE, ...) ```

## 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 `FALSE`) `...` additional plot parameters

None

## Examples

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16``` ```# plot a random mosaic plot(voronoi.mosaic(runif(100),runif(100),duplicate="remove")) # use isometric=TRUE and all=TRUE to see the complete mosaic # including extreme outlier points: plot(voronoi.mosaic(runif(100),runif(100),duplicate="remove"), all=TRUE, isometric=TRUE) # use a part of the quakes data set: data(quakes) quakes.part<-quakes[(quakes[,1]<=-17 & quakes[,1]>=-19.0 & quakes[,2]<=182.0 & quakes[,2]>=180.0),] quakes.vm<-voronoi.mosaic(quakes.part\$lon, quakes.part\$lat, duplicate="remove") plot(quakes.vm, isometric=TRUE) # use the whole quakes data set # (will not work with standard memory settings, hence commented out here) #plot(voronoi.mosaic(quakes\$lon, quakes\$lat, duplicate="remove"), isometric=TRUE) ```
