This function is the quickest way to determine a bounding rectangle for a spatial dataset.
If w is a window, the function
just extracts the outer bounding rectangle
of w as given by its elements xrange,yrange.
The function can also be applied to any spatial dataset that has a window:
for example, a point pattern (object of class "ppp") or
a line segment pattern (object of class "psp").
The bounding rectangle of the window of the dataset is extracted.
Use the function boundingbox to compute the smallest
bounding rectangle of a dataset.
A window (object of class "owin")
of type "rectangle" representing a rectangle.
