Re: [igraph] Question on max id node

If you are using C (I assume you do), try to attach the C attribute  
handler and then read your graph using igraph_read_graph_ncol (this is  
for the NCOL format which is practically a named edge list). This is  
able to store the vertex names used in the NCOL file as a vertex  
attribute. After that, you can scan the attribute values to find the  
largest one.

See http://cneurocvs.rmki.kfki.hu/igraph/doc-0.5/html/ch09s02.html for  
the usage of the C attribute handler.
