Thanks. I understand now.

I found another question.

In igraph
transitivity(g, type="local")
returns NaN for the vertices with degree = 1.

But, in http://arxiv.org/abs/cond-mat/0303516 ,
such vertices have C_i = 0

Is there option that transitivity() returns 0 instead of NaN?

Note the word "connected" here. You can also see
http://arxiv.org/abs/cond-mat/0303516 for an example.
