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.
sample_motifs( graph, size = 3, cut.prob = rep(0, size), sample.size = vcount(graph)/10, sample = NULL )
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 |
sample.size |
The number of vertices to use as a starting point for
finding motifs. Only used if the |
sample |
If not |
sample_motifs
estimates the total number of motifs of a given
size in a graph based on a sample.
A numeric scalar, an estimate for the total number of motifs in the graph.
