Lu,

Thanks for the answer. I had already looked at shp2graph which looked
really fine but that I had trouble installing it properly.

It's nice if we can install it easily now. I'll have to give it a try

To note, also, that the osmar package which provides access to osm data and
coercion to Spatial* Objects can also convert data to igraph objects.

Best,

Mathieu
