[igraph] betweenes and closeness considering time sequences of arcs

[Fabrizio Natale]

Dear all,

I am working with a network representing movements of animals (arcs) between farms (nodes) at given dates.

 

I need to get betweenness and closeness measures of nodes considering only valid paths based on the correct time sequence of the connecting arcs:

a path between A and C passing trough B is valid only if the arc between A and B has a date antecedent to the date of the arc between B and C.

 

Is there already a way of implementing this using igraph?

I would be very thankful if you could help me.
