Graph motifs are small connected induced 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.

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.

Value

count_motifs() returns a numeric scalar.

Details

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