Hi,
I have encountered strange behavior using igraph in R.
shortest.paths command returns correct results, get.shortest.paths returns
warning and no results.
> shortest.paths(g,v=2795,to=2839) # corect
[,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
Does anyone know, whats the problem?
Thanks,
Zbynek_______________________________________________
