##### 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 domain(X).

The exception is that, if X is a point pattern on a linear network (class "lpp") or a point process model on a linear network (class "lppm"), then domain(X) is the linear network on which the points lie, while Window(X) is the two-dimensional window containing the linear network.

The argument from applies when X is a fitted point process model (object of class "ppm" or "kppm"). 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").
