influenceR

influenceR-package

The influenceR package includes functions to quantify the structural
importance of nodes in a network. Algorithms include Betweenness Centrality,
Bridging, Constraint Index, Effective Network Size, and Key Players.
Currently, algorithms are only guaranteed to work on undirected graphs; work
on directed graphs is in progress. These functions run on graph objects from
the igraph package.

Provides functionality to compute various node centrality measures on networks.
Included are functions to compute betweenness centrality (by utilizing Madduri and Bader's
SNAP library), implementations of Burt's constraint and effective
network size (ENS) metrics, Borgatti's algorithm to identify key players, and Valente's
bridging metric. On Unix systems, the betweenness, Key Players, and
bridging implementations are parallelized with OpenMP, which may run
faster on systems which have OpenMP configured.
