Pairwise distances

Computes the matrix of distances between all pairs of `things' in a dataset

Keywords
spatial, math
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.
