From spatstat v1.15-2
by Adrian Baddeley
Convex Hull of Points
Computes the smallest rectangle containing a set of points.
Usage
bounding.box.xy(x, y=NULL)
Arguments
- x
- vector of
x
coordinates of observed points, or a 2-column matrix givingx,y
coordinates, or a list with componentsx,y
giving coordinates (such as a point pattern object of class"ppp"
.) - y
- (optional) vector of
y
coordinates of observed points, ifx
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"
).
