Hi Minh,
Thanks for your answer. Allow me to ask a little bit more.
I just begun my learning about how to use igraph and I am not familiarized
with some command syntax.
To the command "igraph_degree" is informed (igraph_degree(const igraph_t
*graph, igraph_vector_t *res, const igraph_vs_t vids, igraph_neimode_t mode,
igraph_bool_t loops).
Being my graph name "g", in short I understood the syntax as follow:
igraph_degree (g, res, vids, mode, loops).
I don't know what to replace in the fields "res" and "vids".
I tried the follow simplified commands (but they didn't work):
igraph_degree(g)
igraph_degree(g, IGRAPH_ALL, FALSE)
Ps.: The network I am trying this command follows attached (rda format).
All the best,
Cadu

Yes. Check out the documentation of version 0.5.4 of the igraph C library at
http://igraph.sourceforge.net/doc/html/ch10s05.html
The latest development version has library functions following the name
igraph_centralization*.
