domain: Extract the Domain of any Spatial Object

Description

Given a spatial object such as a point pattern, in any number of dimensions, this function extracts the spatial domain in which the object is defined.

Usage

domain(X, ...)
   # S3 method for ppp
domain(X, ...)
   # S3 method for psp
domain(X, ...)
   # S3 method for im
domain(X, ...)
   # S3 method for ppx
domain(X, ...)
   # S3 method for pp3
domain(X, ...)
 # S3 method for quad
domain(X, ...)
 # S3 method for quadratcount
domain(X, ...)
 # S3 method for tess
domain(X, ...)
 # S3 method for layered
domain(X, ...)
 # S3 method for distfun
domain(X, ...)
 # S3 method for nnfun
domain(X, ...)
 # S3 method for funxy
domain(X, ...)

Value

A spatial object representing the domain of X. Typically a window (object of class "owin"), a three-dimensional box ("box3"), a multidimensional box ("boxx") or a linear network ("linnet").

Arguments

X

A spatial object such as a point pattern (in any number of dimensions), line segment pattern or pixel image.

...

Extra arguments. They are ignored by all the methods listed here.

Details

The function domain is generic.

For a spatial object X in any number of dimensions, 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).

Exceptions occur for methods related to linear networks.
