R: Pairwise distances

pairdist {spatstat.geom} | R Documentation

## 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`.
