It is a numeric vector, it is only printed as a string. In the next
igraph version you can use symbolic vertex and edge names, but in the
current version you need to translate them to numeric ids my hand.
This is not hard, if you have your symbolic names in 'symnames', then

ids <- match(symnames, V(g)$id)-1

does the translation.

Best,
