pairdist | R Documentation |
Computes the matrix of distances between all pairs of ‘things’ in a dataset
pairdist(X, ...)
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. |
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.
A square matrix whose [i,j]
entry is the distance
between the ‘things’ numbered i
and j
.
