backbone: Extracts the Backbone from Graphs

Description

Provides methods for extracting from an unweighted and sparse subgraph (i.e., a backbone) that contains only the most "important" edges in a weighted bipartite projection, a non-projection weighted network, or an unweighted network.

Available backbone extraction functions include:

• For weighted bipartite projections of weighted bipartite networks: osdsm().

• For weighted bipartite projections of binary bipartite networks: fixedfill(), fixedrow(), fixedcol(), sdsm(), and fdsm().

• For non-projection weighted networks: global(), disparity().

• For unweighted networks: sparsify(), sparsify.with.skeleton(), sparsify.with.gspar(), sparsify.with.lspar(), sparsify.with.simmelian(), sparsify.with.jaccard(), sparsify.with.meetmin(), sparsify.with.geometric(), sparsify.with.hypergeometric(), sparsify.with.localdegree(), sparsify.with.quadrilateral().

• For all networks: backbone.suggest() will examine the data and suggest an appropriate backbone function

The package also includes some utility functions:

• fastball() - Fast marginal-preserving randomization of binary matrices

• bicm() - Compute probabilities under the bipartite configuration model
