distGraph-class

Class "distGraph"

A class definition for graphs that are based on distances.

Objects can be created by calls of the form new("distGraph", ...).

Dist:: Object of class "dist" that forms the basis for the edge weights used in the distGraph.

Class "graph", directly.

show: signature(object = "distGraph"): a print method
Dist: signature(object = "distGraph"): return the dist object.
adj: signature(object = "distGraph"): find the nodes adjacent to the supplied node.
nodes: signature(object = "distGraph"): return the nodes in the graph.
numNodes: signature(object = "distGraph"): return the number of nodes.
threshold: 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).
initialize: signature(object = "distGraph"): initialize a distGraph instance.
edgeWeights: Return a list of edge weights in a list format similar to the edges method.
edgeL: signature(graph = "distGraph"): A method for obtaining the edge list.
