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.

domain(X, ...)
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").
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.

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.
