4 years ago These numbers are node indices for the "phylo" object. There specific values are meaningless; except that (by convention) the values 1:N for N tips are assigned to external nodes, the values (N+1):(N+m) for m internal nodes are assigned to internal nodes, and the value N+1 is assigned to the global root.

Work on a figure like the one shown above. Could you please tell me what does the edge number meaning? Or it's just numbers and don't mean anything? Thanks.
