Use this if you are using igraph from R
Graph motifs are small connected subgraphs with a well-defined structure. These functions search a graph for various motifs.
count_motifs(graph, size = 3, cut.prob = rep(0, size))
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 |
count_motifs
calculates the total number of motifs of a given
size in graph.
count_motifs
returns a numeric scalar.
