frag.diameters {archeofrag}

Diameter distribution for unconnected graphs

Description

Returns the distribution of the diameter values of a fragmentation graph.

Usage

frag.diameters(graph, cumulative = FALSE)

Arguments

graph

An igraph object.

cumulative

Logical. If TRUE the cumulative relative frequency of the diameters is reported.

Details

frag.diameters wraps the igraph diameter function. For graphs representing the fragmentation of archeological objects, the diameter of each component of the graph (i.e. archeological objects) can be interpreted: as a measure of the intensity of fragmentation (when all the fragments of the initial object are known); as a measure of the scattering of the fragments (when not all the fragments are known);

Value

A numeric vector of the length equal to the maximum diameter value found. The first element is the frequency of the diameter values = 1, the second element is the frequency of diameter values = 2, etc. If cumulative is True, the cumulative density is returned.
