Re: [igraph] Distance along a road

[Gábor Csárdi]

Hi Ashly,

if you can convert your data to an igraph graph, then the
get.shortest.paths() function will calculate the shortest way to get
from one node (city) to another.

I am not familiar with shapefiles, though, so I don't know how to
convert them to igraph.
