domain.lpp: Extract the Linear Network on which Spatial Data are Defined

Description

Given a spatial object representing data on a linear network, extract the network.

Usage

domain(X, ...)
 # S3 method for linfun
domain(X, ...)
 # S3 method for lintess
domain(X, ...)

Value

A linear network (object of class "linnet").

Arguments

X

A spatial object representing data on a linear network. An object of class "lpp", "lppm", "linfun" or "lintess".

Details

The function domain is generic, with methods for many classes.

For a spatial object X domain(X) extracts the spatial domain in which X is defined.

For a two-dimensional object X, typically domain(X) is the same as Window(X).

The exception is that, if X is a point pattern on a linear network (class "lpp") or a point process model on a linear network (class "lppm"), then domain(X) is the linear network on which the points lie, while Window(X) is the two-dimensional window containing the linear network.
