R: Pairwise distances

crossdist {spatstat} | R Documentation

## Pairwise distances

### Description

Computes the distances between pairs of ‘things’ taken from two different datasets.

### Usage

      crossdist(X, Y, ...)

### Arguments

`X,Y` | Two objects of the same class.
`...` | Additional arguments depending on the method.

### Details

Given two datasets `X` and `Y` (representing either two point patterns or two line segment patterns) `crossdist` computes the Euclidean distance from each thing in the first dataset to each thing in the second dataset, and returns a matrix containing these distances.

The function `crossdist` 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 `crossdist.ppp`, `crossdist.psp` or `crossdist.default` for further details.

### Value

A matrix whose `[i,j]` entry is the distance from the `i`-th thing in the first dataset to the `j`-th thing in the second dataset.
