Igraph coreness
Did you know?
WebR coreness. The k-core of graph is a maximal subgraph in which each vertex has at least degree k. The coreness of a vertex is k if it belongs to the k-core but not to the (k+1) … Web2.2. igraph_shortest_paths_dijkstra — Weighted shortest paths from some sources. This function is Dijkstra's algorithm to find the weighted shortest paths to all vertices from a single source. (It is run independently for the given sources.) It …
WebDetails. The shortest path, or geodesic between two pair of vertices is a path with the minimal number of vertices. The functions documented in this manual page all calculate shortest paths between vertex pairs. distances () calculates the lengths of pairwise shortest paths from a set of vertices ( from) to another set of vertices ( to ). http://www.endmemo.com/r/coreness.php
WebFor is_connected () a logical constant. For components () a named list with three components: membership. numeric vector giving the cluster id to which each vertex belongs. csize. numeric vector giving the sizes of the clusters. no. numeric constant, the number of clusters. For count_components () an integer constant is returned. http://giorgidze.github.io/igraph/Data-IGraph.html
