Pairwise shortest-path distances between points on a linear network

Given a pattern of points on a linear network, compute the matrix of distances between all pairs of points, measuring distance by the shortest path in the network.

Keywords
spatial
Usage
## S3 method for class 'lpp':
pairdist(X, ..., method="C")
Arguments
X
Point pattern on linear network (object of class "lpp").
method
Optional string determining the method of calculation. Either "interpreted" or "C".
...
Ignored.
Details

Given a pattern of points on a linear network, this function computes the matrix of distances between all pairs of points, measuring distance by the shortest path in the network. If method="C" the distances are computed using code in the C language. If method="interpreted" then the computation is performed using interpreted Rcode. The Rcode is much slower, but is provided for checking purposes.

Value

  • A symmetric matrix.
