[igraph] Counting stars and cliques

[Jonathan Donges]

Hi List,

I would like to count the number of stars and cliques of a certain order 
(number of nodes) that are contained in a graph. For orders 3 and 4, I use the 
motif_randesu() method.

Two questions arise:

1. Is there a more efficient way than counting all motifs, since I am only 
interested in stars and cliques here?

2. Is there an easy way in igraph to generalize motif_randesu for higher order 
motifs, i.e., size>4? Particularly, for counting stars and cliques with size>4?

Cheers!
Jonathan
