Extracts the Backbone from Networks R package backbone version 3.0.4 CRAN Task View: GraphicalModels (https://CRAN.R-project.org/view=GraphicalModels) CRAN Task View: NetworkAnalysis (https://CRAN.R-project.org/view=NetworkAnalysis) An implementation of methods for extracting a sparse unweighted network (i.e. a backbone) from an unweighted network (e.g., Hamann et al., 2016 <doi:10.1007/s13278-016-0332-2>), a weighted network (e.g., Serrano et al., 2009 <doi:10.1073/pnas.0808904106>), or a weighted projection (e.g., Neal et al., 2021 <doi:10.1038/s41598-021-03238-3>).
