Let's clarify the issue first. Are you using read.graph(filename, 
format="edgelist") or something else? How does your file look like? Is it only 
two columns with some numbers? Are your vertex indices (i.e. the numbers) 
continuous from 0 to N-1, where N is the number of vertices in the graph? If 
not, have you tried using read.graph(filename, format="ncol") instead? ncol is 
basically a symbolic edge list where vertices are assigned IDs from 0 to N-1 in 
the order of appearance and the numbers in the file (that are used to identify 
the vertices) are stored in the "name" vertex attribute.

Best,
T.
