compGdist R Documentation
A function to compute the distance between pairs of nodes in a graph.
Description
Given a graph, g, and a set of nodes in the graph,
whNodes, Dijkstra's shortest path algorithm is used to compute
the distance between all pairs of nodes in whNodes.
Usage
compGdist(g, whNodes, verbose = FALSE)
Arguments
g
An instance of the graph class.
whNodes
A vector of lables of the nodes in g for which
distances are to be computed.
verbose
If TRUE then output reporting the progress will
be reported.
Details
This function can be quite slow, computation of the pairwise
distances is not especially fast and if whNodes is long then
there are many of them to compute.
Value
A matrix containing the pairwise distances. It might be worth making
this an instance of the dist class at some point.
