multifurcating nodes

[daniel...@gladstone.ucsf.edu]

Hi,

Does the dendrogram class accept trees/graphs that are not binary?

That is, does it allow nodes to have more than two child nodes?

I realize this is a general R dendrogram question and not specific to phylogram.

Thanks in advance for your help!
Dan.

Hi Dan,

Yes, dendrograms can have multifuricating nodes; these objects are just lists of lists (with additional attributes), which can theoretically be any length you like.

For example the Newick string (A:0.1,B:0.2,(C:0.3,D:0.4):0.5); has three nodes at the first level.

Hope that helps, and please let me know if you have any more questions!

Cheers,

Shaun

Nevermind. I just checked and it does allow it.
