Hi all, I am trying to analyze some graphs in R. Given a weighted directed network with 7 nodes. I want to find a path from node 1 to node 7, so the sum of all the edges on the path is the smallest comparing to all the other paths. I am wondering if I can do this in igraph. After I identify the path, can I colour code the path? Thank you in advance.
