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

## S3 method for class 'ppm'
domain(X, ..., from=c("points", "covariates"))

 ## S3 method for class 'kppm'
domain(X, ..., from=c("points", "covariates"))

 ## S3 method for class 'dppm'
domain(X, ..., from=c("points", "covariates"))

 ## S3 method for class 'msr'
domain(X, ...)

 ## S3 method for class 'quadrattest'
domain(X, ...)

 ## S3 method for class 'rmhmodel'
domain(X, ...)

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.

from

Character string. See Details.

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.

The argument from applies when X is a fitted point process model (object of class "ppm", "kppm" or "dppm"). If from="data" (the default), domain extracts the window of the original point pattern data to which the model was fitted. If from="covariates" then domain returns the window in which the spatial covariates of the model were provided.

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").
