Hi,

I am new to igraph and confused about the starting index for vertex.

Many documentation says that starting index for vertex in R is 0.

Where? These are outdated or wrong. See e.g. ?igraph.

But on R I get the starting index as 1.

Please following

> V(kap)[0]

Vertex sequence:

character(0)

> V(kap)[1]

Vertex sequence:

[1] "moskowitz"
