Use list.vertex.attributes(G18) to list the names of the vertex attributes in 
your graph. It could be the case that the names are stored in a different 
vertex attribute and not "name"; it all depends on how you saved the GraphML 
file from the software you were creating it with. That software could have 
stored the vertex names in "name", "Name", "label", "Label" or any other vertex 
attribute.
