ape 1.0 is on CRAN
Dear all,
The version 1.0 of ape (analysis of phylogenetics and evolution) is now on
CRAN. The jump from version 0.2-1 to 1.0 is explained by the fact that the
initial objectives of the project have been completed. The relevant part of
the Changes file is shown below. All comments, suggestions, or bug reports
are welcome.

Obtaining r-squared values from phylogenetic autoregression in ape
Hello,
I am trying to carry out a phylogenetic autoregression to test whether my
data show a phylogenetic signal, but I keep calculating bizzare R-squared
values.

Using ACE in the ape package
Having a problem running the ace command in ape.
After reading my table into R and then putting the names of the rows in the
table in same order as the tree I can't get ace to run and get the message
Erreur dans as.matrix(x) :
dims [produit 25] ne correspond pas ? la longueur de l'objet [0]
This is the command I am using and each of the vectors used in the

Dice dissimilarity output and 'phylo' function in R
Dear All,
I get some problems using the 'phylo' and
dissimilarity functions in R. I converted an output
from 'hclust' into an order of phylo so as to be able
to use the 'consensus' function on it. Each time I
submit the consensus codes, my computer hangs. When I
tried to see what the contents of the object converted
into order phylo is, I get the message

APE: compar.gee( )
Dear all,
I don't understand the following behaviour: Running compar.gee (in
library ape ) with and without the option 'data', it give me different
results

Rooting trees using ape
Hi all,
I seem to be having a difficult time using the 'ape' package in R
when it comes to rooting trees. Here's a short screenshot:

Tip labels:

Ralstonia2, ...
Node labels:

help on drawing a tree with "ape"?
Dear all,
I'm using the "ape" package in R and want to draw a
phylogenetic tree with not only the tip labels but
also some labels for the edges. e.g. Mark the edge AB
as "m" in the tree ABC.
Couldn't find a way to do that. Can someone help?
Thanks,

possible bug in ape::extract.clade()
Hi,
I was recently splitting some massive phylo class objects with extract.clade()
and noticed what appears to be a bug in how tip labels are copied from the
full tree to the pruned tree. This possible bug was also mentioned here:
http://www.mail-archive.com/r-sig-phylo at r-project.org/msg00537.html
An example:

Help with ape - read.GenBank()
Hi,
I am trying to work with the ape package, and there is one thing I am
struggling with. When calling the *read.GenBank()* function, I can get it
to work with an object created like this:
*>x <- c("AY395554","AY611035", ...)*
*>read.GenBank(x)*
However, I am trying to use the function to fetch several hundred sequences
at once. So I have been testing with small

Any functions to manipulate (merge, cut, remove) hclust objects? (maybe through phylo?)
Hello all,
I'm now working with hclust objects and was hoping to perform some basic
editing on them like:
- Joining = the merging of two hclust objects (so they will share one
root)
- Splicing = So to cut/extract a branch out of an hclust object - that by
itself will be an hclust object.
I noticed I could extract one element of an hclust object by turning it into
a dendrogram,

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

ape comparative analysis query
I've been comparing variables among objects (taxa) related by known
trees, using phylogentically independent contrasts in the ape package,
and want to move on to more complex models e.g. by using gls with
appropriate correlation terms. My trees contain lots of (hard)
polytomies and information about ancestors, which I've been including-
creating fully dichotomous trees by using zero branch

Cannot convert from phylo to hclust , error!!???
Hello,
The following code does'nt work for me. The last command reports an error. I
have created a consensus tree using the consensus comand from phylo but
cannot manipulate the phylo object afterwards to create a dendogram , by
transforming the phylo object into a hclust object and then into a dendogram
??

convert non-ultrametric phylo to dendrogram
I am beginning to work with the 'ape' package in R, and have run into some
trouble. I generated a UPGMA tree based on DNA sequence distance in Paup*
and read it into R, where it became an object of class "phylo". However, I
need it to be classified as a "dendrogram" for my purposes (to use it to
order the layout of a heatmap). I get an error using as.hclust.phylo

How to colour the tip labels in a phylogenetic tree
Hi,
Using Ape, I have constructed an object of class "phylo", using the
method 'nj' (lets call the object 'tree_ja').
I also have a given subset of 'tree_ja' in a vector (lets call the
vector 'subspecies').
What I want to do, is construct a nj tree - plot(tree_ja) - but have the
species in vector 'subspecies' shown as red at the tips of the

Is there some command or alternative using dist.dna in ape package for models not included like GTR?
Hi,
I am making some DNA distances and I would like to use dist.dna as matrix in
R, but this command does not include models like GTR...
Is there some command or alternative using dist.dna in ape package for
models not included like GTR?
I would appreciate any help given

peering inside functions in a package?
Let's say I would like to look inside the function corBrownian in library
(ape). When I type in the function name I get the following, which is not
nearly the detail that goes into this function. I am wondering how to
begin cracking this function open (and others) so I can learn more about it
and perhaps code my own corClass one day. Thanks.

Package for phylogenetic tree analyses
Hi
I am looking for a package that
1. reads in a phylogenetic tree in NEXUS format
2. given two members/nodes on the tree, can return the
distance between the two using the tree.
I came across the following packages on CRAN
ouch, ape, apTreeShape, phylgr all of which seem to
provide extensive range of functions for reading in a
