Description

Extract a subset of a window.

Usage

  ## S3 method for class 'owin'
x[i, ...]

Arguments

x	A spatial window (object of class "owin").
i	Object defining the subregion. Either a spatial window, or a pixel image with logical values.
...	Ignored.

Details

This function computes the intersection between the window x and the domain specified by i, using intersect.owin.

This function is a method for the subset operator "[" for spatial windows (objects of class "owin"). It is provided mainly for completeness.

The index i may be either a window, or a pixel image with logical values (the TRUE values of the image specify the spatial domain).
