[igraph] How to resolve this problem: At vector.pmt:409 : cannot reserve space for vector, Out of memory

[shahab mokarizadeh]

Hi,
I am using R-IGraph and I  load a directed graph with 138973 vertices
and  733813 edges. I could load the graph with no problem.
Then I invoked " shortes.path(mygraph) " where I get the following exception:
Error in shortest.paths(myraph) :
    At vector.pmt:409 : cannot reserve space for vector, Out of memory

I am using Widnows x64 with 3G RAM. I tried both Rterm.exe and
Rgui.exe with following options, but it didn't make any change:
  --min-vsize=2G --min-nzise=19173961 (1G)  or
  --min-visize=3G

Is there anything that I am missing in memory setting or simply the
graph is so large?

Thanks,
