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.
