##### Smallest Enclosing Circle

Find the smallest circle enclosing a spatial window or other object. Return its radius, or the location of its centre, or the circle itself.

Keywords
spatial, math
##### Usage
boundingradius(x, …)boundingcentre(x, …)boundingcircle(x, …)# S3 method for owin
boundingradius(x, …)# S3 method for owin
boundingcentre(x, …)# S3 method for owin
boundingcircle(x, …)# S3 method for ppp
boundingradius(x, …)# S3 method for ppp
boundingcentre(x, …)# S3 method for ppp
boundingcircle(x, …)
##### Arguments
x

A window (object of class "owin"), or another spatial object.

Arguments passed to as.mask to determine the pixel resolution for the calculation.

##### Details

The boundingcircle of a spatial region $W$ is the smallest circle that contains $W$. The boundingradius is the radius of this circle, and the boundingcentre is the centre of the circle.

The functions boundingcircle, boundingcentre and boundingradius are generic. There are methods for objects of class "owin", "ppp" and "linnet".

##### Value

The result of boundingradius is a single numeric value.

The result of boundingcentre is a point pattern containing a single point.

The result of boundingcircle is a window representing the boundingcircle.
