Re: [igraph] extracting lists

[Thiago M. Venancio]

Hi,

The file graph.txt is a ncol format graph.
I got a clue here. What happens is that the V(graph) command returns an integer type data that starts in the position zero. So, the degree in deg[1] is relative to vec[0] vertex.
I would like to transform the vec (integer type) to get a vector with node names (not numerical IDs). Every time I use as.vector and relative commands I get the numerical IDs and not the names.

Hope you can help me now with the additional info provided.

Thanks.

Thiago

Hi,

it is hard to guess what is in 'graph.txt', but 'deg' and 'vec' are
"in order" here, i.e. deg[1] belongs to vec[1], etc.

You need to give us a reproducible example to see what goes wrong for you.
