[R] Binary Tree Testing in "ape" package (a bug?)

[Gundala Viswanath]

Dear all,

I was testing the wonderful package APE.

However upon testing a particular Newick's format
tree - which I think to be a non-binary tree -
it yields different result as expected.

> library(ape)
> tree.hiv <- read.tree(text="(rat,mouse,(human,chimp));")
> is.binary.tree(tree.hiv)
[1] TRUE

Was that a bug in APE package?
