Convex Hull of Points

Computes the smallest rectangle containing a set of points.

Keywords
utilities, spatial
Usage
bounding.box.xy(x, y=NULL)
Arguments
x
vector of x coordinates of observed points, or a 2-column matrix giving x,y coordinates, or a list with components x,y giving coordinates (such as a point pattern object of class "ppp".)
y
(optional) vector of y coordinates of observed points, if x is a vector.
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").
