Pairwise distances
Description
Computes the matrix of distances between all pairs of ‘things’ in a dataset
Usage
pairdist(X, ...)
Arguments
X |
Object specifying the locations of a set of ‘things’ (such as a set of points or a set of line segments). |
... |
Further arguments depending on the method. |
Details
Given a dataset X and Y
(representing either a point pattern or
a line segment pattern)
pairdist computes the distance between each pair of
‘things’ in the dataset, and returns
a matrix containing these distances.
The function pairdist is generic, with
methods for point patterns (objects of class "ppp"),
line segment patterns (objects of class "psp")
and a default method. See the documentation
for pairdist.ppp, pairdist.psp
or pairdist.default for details.
Value
A square matrix whose [i,j] entry is the distance
between the ‘things’ numbered i and j.
