Pairwise Distances in Any Dimensions
Computes the matrix of distances between all pairs of points in a multi-dimensional point pattern.

This is a method for the generic function pairdist.
Given a multi-dimensional point pattern X
(an object of class "ppx"),
this function computes the Euclidean distances between all pairs of
points in X, and returns the matrix of distances.
By default, both spatial and temporal coordinates are extracted.
To obtain the spatial distance between points in a space-time point
pattern, set temporal=FALSE.
A square matrix whose [i,j] entry is the distance
between the points numbered i and j.
