Binary Tree Testing in "ape" package (a bug?)
If I am right informed, 'is.binary.tree' cannot test for root polytomies. Consider this example: tree.hiv <- read.tree(text="((rat,mouse,(human,chimp)), kangaroo);") is.binary.tree(tree.hiv) # will yield 'FALSE' For further questions you might be better advised to use the 'R-sig- phylo' mailing list. ________________________________________________________ Christoph Heibl Systematic Botany Ludwig-Maximilians-Universit?t M?nchen Menzinger Str. 67 D-80638 M?nchen GERMANY phone: +49-(0)89-17861-251 e-mail: heibl at lmu.de http://www.christophheibl.de/ch-home.html

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? - Gundala Viswanath Jakarta - Indonesia
