[igraph] memory problem

[paolo]

Hi,

I'm trying to compute the shortest path for a weighted network with around 170000 vertices and 201000 edges. This is what happens:

 

> s<-shortest.paths(g,weights = NULL)

Error in shortest.paths(g, weights = NULL) :

  At vector.pmt:408 : cannot reserve space for vector, Out of memory

 

I run Igraph on R, windows XP, with an intel core 2, CPU T7400 at 2.16GHz, with 2GB of RAM.

I attach the network I'm trying to work on.

Do you think there is any chance I can sort it out?

My best regards

Paolo
