Graph motifs

Graph motifs are small connected subgraphs with a well-defined structure. These functions search a graph for various motifs.

Usage
count_motifs(graph, size = 3, cut.prob = rep(0, size))
Arguments
graph
Graph object, the input graph.
size
The size of the motif, currently 3 and 4 are supported only.
cut.prob
Numeric vector giving the probabilities that the search graph is cut at a certain level. Its length should be the same as the size of the motif (the size argument). By default no cuts are made.
Details

count_motifs calculates the total number of motifs of a given size in graph.

Value

  • count_motifs returns a numeric scalar.
