if I type

printf("number of nodes: %d\n", igraph_vcount(graph));

If you are using R, then it's vcount()

I need to allocate a vector of the same size of the number of nodes, in order to use clustering functions. How do I call that function?

Thanks in advance

   Hi,

   The basic built in function summary() can help you get the number
