[igraph] In trouble with subgraph

[Chang Jin Shin]

Hi Gabor

I have in trouble in extracting subgraph.

Example:

g <- graph.ring(10)
g2 <- subgraph(g, c(2,4))

I got error message.
-------------------------------
G <- graph.ring(10)
n <- neighbors(g, 3)
G2 <- subgraph(g, n)

I got error too.
-------------------------------


The components which I want to extract from the original network
are not consecutive numbers. How can I do?


With regards,
