WindowOnly: Extract Window of Spatial Object

Description

Given a spatial object (such as a point pattern or pixel image) in two dimensions, these functions extract the window in which the object is defined.

Usage

# S3 method for ppm
Window(X, …, from=c("points", "covariates"))
 # S3 method for kppm
Window(X, …, from=c("points", "covariates"))
 # S3 method for dppm
Window(X, …, from=c("points", "covariates"))
 # S3 method for lpp
Window(X, …)
 # S3 method for lppm
Window(X, …)
 # S3 method for msr
Window(X, …)
 # S3 method for quad
Window(X, …)
 # S3 method for quadratcount
Window(X, …)
 # S3 method for quadrattest
Window(X, …)
 # S3 method for tess
Window(X, …)
 # S3 method for layered
Window(X, …)
 # S3 method for distfun
Window(X, …)
 # S3 method for nnfun
Window(X, …)
 # S3 method for funxy
Window(X, …)
 # S3 method for rmhmodel
Window(X, …)
 # S3 method for leverage.ppm
Window(X, …)
 # S3 method for influence.ppm
Window(X, …)

Arguments

X

A spatial object.

…

Ignored.

from

Character string. See Details.

Value

An object of class "owin" (see owin.object) specifying an observation window.

Details

These are methods for the generic function Window which extract the spatial window in which the object X is defined.

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