[igraph] Global characteristics in a network

[Qunawei Zhang]

Hello:

I want to include some global information about the network in our study. Now I considered the following characteristics: the number of nodes, number of edges, global clustering coefficient, diameter, radius, density, average number of neighbors and average shortest paths.  I wonder whether there are some other informative global characteristics I can get by the package. 

BTW, would you please tell me how to cite it if I use Igraph in my study?

Thanks

Best
