## Graph motifs

### Description

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. 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.

isomorphism_class

Other graph motifs: motifs(), sample_motifs()

### Examples

g <- barabasi.game(100)
motifs(g, 3)
count_motifs(g, 3)
sample_motifs(g, 3)
