In DarioS/ClassifyR: A framework for cross-validated classification problems, with applications to differential variability and differential distribution testing

Convert a Two-column Matrix or Data Frame into a Hub Node List

Description

Interactions between pairs of features (typically a protein-protein interaction, commonly abbreviated as PPI, database) are restructured into a named list. The name of the each element of the list is a feature and the element contains all features which have an interaction with it.

Usage

edgesToHubNetworks(edges, minCardinality = 5)

Arguments

edges	A two-column matrix or data.frame for which each row specifies a known interaction betwen two interactors. If feature X appears in the first column and feature Y appears in the second, there is no need for feature Y to appear in the first column and feature X in the second.
minCardinality	An integer specifying the minimum number of features to be associated with a hub feature for it to be present in the result.

Value

An object of type FeatureSetCollection.
