Hi,I hope this is a very simple newbie question! Can you please confirm that vertex numbering starts with zero (for the C-library version of iGraph, as is discussed in the introduction of the reference manual [1])? I ask this because I just read the documentation on igraph_subgraph() [2] which seems to indicate that numbering starts with one.
