[R-sig-Geo] Create a Spatial Weight Matrix based on road distance

[Rolando Valdez]

Dear community,

Is there any way to create a spatial weight matrix based on road distance?
I am trying to use the road distance between two points instead of
euclidean distance.

I've seen that there is a package named osrm. Can anyone give some advice?

Thank you in advance.

Regards,
