bounding.box.xy {spatstat.geom} | R Documentation |
Convex Hull of Points
Description
Computes the smallest rectangle containing a set of points.
Usage
bounding.box.xy(x, y=NULL)
Arguments
x |
vector of |
y |
(optional) vector of |
Details
Given an observed pattern of points with coordinates
given by x
and y
, this function finds the smallest
rectangle, with sides parallel to the coordinate axes, that contains
all the points, and returns it as a window.
Value
A window (an object of class "owin"
).
