Re: [igraph] question from a beginner

Hi,

in R? Python? C? 

Anyway, first create a long vector that contains the edges of your graph, and then use the regular igraph constructors, e.g. graph() in R.

Hi everyone,

I'm a beginner in igraph. I have one simple question:

there is a file route.txt as below:

AS3 AS6 AS10 AS1
AS56 AS23 AS36 AS1
AS123 AS568 AS2 AS45 AS36 AS1
AS79 AS1

AS* represents a network node, and each line represents a route,for example: AS3->AS6->AS10->AS1 (line 1)

how to create a tree graph from this file?

Thanks!
