calculate.delta {incgraph}R Documentation

Calculate changes in orbit counts

Description

calculate.delta calculates the changes in orbit counts as a result of a single edge modification.

Usage

calculate.delta(network, i, j)

Arguments

network

An instance of the incgraph.network class

i

A node in network

j

A node in network

Details

This method iterates over and counts all graphlets which were added to or removed from the network due to one edge modification.

Value

A list containing two N-by-73 matrices, with N the number of nodes in the network and 1 column for each possible orbit. The value of list$add[i,j] (resp. list$rem[i,j]) is the number of times a subgraph was added to (resp. removed from) the network such that node i has orbit j in that subgraph.
