Error with shortest.path function in R

0 votes

I'm facing some issues with shortest.path function.

shortest.paths(g, v=2795, to=2839) # correct

         [,1]
    [1,] 3930.4

get.shortest.paths(g, from=2795, to=2839) # warning and no results

    [[1]]

    numeric(0)

Warning message:
In get.shortest.paths(g_novy, from = 2795, to = 2839) :
  At structural_properties.c:5296 :Couldn't reach some vertices

you have a directed graph. The shortest.paths function will tell you the length of the shortest undirected path. The get.shortest.paths function tells you that there is no directed path between the vertices.
