Computes the smallest rectangle containing a set of points.

1	bounding.box.xy(x, y=NULL)

`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.

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.

A window (an object of class "owin").
