Hi, this is intentional and yes, it is confusing. The solution
would be using 1-based indexing for vertex and edge ids in igraph,
but this is not trivial and will break almost all the existing R code.

Or the other solution would be to just change the indexing of
V(g), but that would be also confusing, since  V(g)[1] would mean
vertex 0.

Something will be done, maybe in the next major release, but
i haven't decided yet.
