First of all, in an igraph graph the vertices are numbered from zero,
it seems that you were not aware of that. It is the number one igraph
catch.

No, this is not the way how subgraph() works, it just calculates the
induced subgraph, see
http://en.wikipedia.org/wiki/Induced_subgraph#Subgraphs

Perhaps what you are looking for is neighborhood() or neighborhood.graph().

Best,
G.
