bounding.box {spatstat} | R Documentation |
Find the smallest rectangle containing a given window(s)
bounding.box(...)
... |
One or more windows (objects of class "owin" ). |
If the argument is a single window object w
,
this function finds the smallest rectangle (with sides parallel to
the coordinate axes) containing w
.
If the argument is a list of windows, then this function finds the smallest rectangle that contains all of the windows.
Note that the bounding box of a window w
is usually smaller than
the window frame (determined by w$xrange
and
w$yrange
and extracted by as.rectangle
).
A window (object of class "owin"
)
of type "rectangle"
representing a rectangle.
