Pairwise distances
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' numberediandj.
