plot.lintess: Plot a Tessellation on a Linear Network

Description

Plot a tessellation or division of a linear network into tiles.

Usage

# S3 method for lintess
plot(x, …,
        main, add = FALSE, style = c("segments", "image"), col = NULL)

Arguments

x

Tessellation on a linear network (object of class "lintess").

…

Arguments passed to segments (if style="segments") or to plot.im (if style="image") to control the plot.

main

Optional main title for the plot.

add

Logical value indicating whether the plot is to be added to an existing plot.

style

Character string (partially matched) indicating whether to plot the tiles of the tessellation using segments or to convert the tessellation to a pixel image and use plot.im.

col

Vector of colours, or colour map, determining the colours used to plot the different tiles of the tessellation.

Value

(Invisible) colour map.

Details

A tessellation on a linear network L is a partition of the network into non-overlapping pieces (tiles). Each tile consists of one or more line segments which are subsets of the line segments making up the network. A tile can consist of several disjoint pieces.

This function plots the tessellation on the current device. It is a method for the generic plot.

If style="segments", each tile is plotted using segments. Colours distinguish the different tiles.

If style="image", the tessellation is converted to a pixel image, and plotted using plot.im.
