[R] igraph problem

Run this code

graph.bfs(tree,root=1, neimode="out",father=TRUE,order=TRUE,unreachable =

I do not understand why the father values will give NA 1 1 3 1 rather than NA
1 1 1 3

The reason I am doing this is to obtain the values(by vertex names) or some
index of each individual branch in tree. Does anyone have any ideas on how
to do this?

Yours sincerely,
