##### 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.

##### Examples

```
# NOT RUN {
g <- barabasi.game(100)
motifs(g, 3)
count_motifs(g, 3)
sample_motifs(g, 3)
# }
```
