[igraph] Named vertexes from imported adjacency matrix

[Szabolcs Feczak]

Hi,

I have just started to use this tool with R, so far I have achieved
to read my adjacency matrix from CVS and plot the graph (with the method below),
however I would like to have the vertex labels as the identifiers
on the rows/columns not the automatically assigned numbers
how can I do this automatically (I have more actors, the below is just a truncated file)



Thanks

S.

ps: great tool
