netUtils

Network utility functions

netUtils is a collection of tools for network analysis that may not deserve a package on their own and/or are missing from other network packages.

Installation

You can install the development version of netUtils with:

# install.packages("remotes")
remotes::install_github("schochastics/netUtils")

Functions

most functions only support igraph objects

helper/convenience functions
biggest_component() extracts the biggest connected component of a network.
delete_isolates() deletes vertices with degree zero.
bipartite_from_data_frame() creates a two mode network from a data frame.
graph_from_multi_edgelist() creates multiple graphs from a typed edgelist.
clique_vertex_mat() computes the clique vertex matrix.
graph_cartesian() computes the Cartesian product of two graphs.
graph_direct() computes the direct (or tensor) product of graphs.
str() extends str to work with igraph objects.

methods
triad_census_attr() calculates triad census with vertex attributes.
core_periphery() fits a discrete core periphery model.
graph_kpartite() creates a random k-partite network.
sample_coreseq() creates a random graph with given coreness sequence.
sample_pa_homophilic() creates a preferential attachment graph with two groups of nodes.
structural_equivalence() finds structurally equivalent vertices.
fast_clique() computes cliques with MACE (faster than igraph for dense graphs).

methods to use with caution
(this functions should only be used if you know what you are doing)
as_adj_list1() extracts the adjacency list faster, but less stable, from igraph objects.
as_adj_weighted() extracts the dense weighted adjacency matrix fast.
