Hi guys of the (R) igraph community.

I have a
question for you, I already read several manuals but I still don't
understand how to get, on igraph, an Undirected scale free network with
n vertices and a givenĀ average degree (for example, average degree of
all vertexes = 8).

Do you have any suggestions?

Another way to get it, I think, is to force the network to have a given number of edges, since the average degree is 2M/N, where M is the total number of edges and N is the total number of vertices.

Thank you, and sorry for my bad english, I am from Italy.
