Extract Subset of Window
Extract a subset of a window.
## S3 method for class 'owin' x[i, ...]
x |
A spatial window (object of class |
i |
Object defining the subregion. Either a spatial window, or a pixel image with logical values. |

Ignored. |
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).
Another spatial window (object of class "owin").
