What is the point of this line?

This gives me:
Error: unexpected '}' in:
"neigh_size <-sapply(graph.neighborhood(karate,1,nodes=V(karate)),
function(g) {
sizes(wckarate)[membership(wckarate)[V(g)] }"

Yes, this is very inconvenient, and will be fixed in the next major
release. Until then, you can just index V(karate)$name with the numeric ids
to get the symbolic ids.
