informationLayerIndex: Information layer index

Description

This method calculates the information layer index of a graph.

Usage

informationLayerIndex(g, dist=NULL, layer=NULL)

Arguments

g

a graph as a graphNEL object.

dist

the distance matrix of the graph. Will be calculated automatically if not supplied.

layer

the layer (sphere) matrix of the graph. Will be calculated automatically if not supplied.

Value

The information layer index as a double-precision floating point value.

Examples

set.seed(987)
g <- randomEGraph(as.character(1:10), 0.3)

dist <- distanceMatrix(g)
layer <- layerMatrix(g, dist=dist)
