| distGraph-class {graph} | R Documentation |
A class definition for graphs that are based on distances.
Objects can be created by calls of the form new("distGraph", ...).
Dist:"dist" that forms the
basis for the edge weights used in the distGraph.
Class "graph", directly.
signature(object = "distGraph"): a print methodsignature(object = "distGraph"): return the dist
object. signature(object = "distGraph"): find the nodes
adjacent to the supplied node. signature(object = "distGraph"): return the
nodes in the graph. signature(object = "distGraph"): return the
number of nodes. signature(object = "distGraph", k, value): set all
distances that are larger than the supplied threshold, k, to the
supplied value. The default is value is zero (and so is appropriate for
similarities, rather than distances). signature(object = "distGraph"):
initialize a distGraph instance. edges method.
