The file format is correct and I have checked its display in Mesquite, which exported the nexus file (I've pasted the text of

Dear all, I wanted to let you know about four phylogenetic comparative methods (PCM) packages that have become available on (3 on CRAN and 1 on GitHub) recently that hopefully will be interesting to somebody. Three of them go significantly beyond the Brownian motion (BM) and Ornstein-Uhlenbeck (OU) processes. 1) There is a new version of mvSLOUCH available. The most important change is that the

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. My script is: > library(ape) > x <-

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

I'm trying to select a model under PCA using independent contrasts. Since PICs need to be forced through the origin I've been using lmorigin for the original regression, but it doesn't appear that stepAIC recognizes it. I keep receiving an error message - "Error in na.fail.default(list(Phenology = c(NA_integer_, NA_integer_, : missing values in object" I'm having

Hi, I'm trying to build a mixed-effects model in which I'd like to include either a distance matrix or a phylogenetic tree as a random effect. The troubles I've had are that: 1. Function lmer() in package lme4 only accepts a data frame column as a random factor and not a distance matrix. 2. Function MCMCglmm() in package MCMCglmm only accepts a rooted and ultrametric phylogenetic

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. Emmanuel Paradis CHANGES IN APE VERSION 1.0 NEW FEATURES

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

Can you recommend an R library that will help me create a diagram of a phylogenetic tree on which specific images are placed at appropriate nodes of the tree? For example, I have specific image files associated with each member of the phylogenetic tree, and I would like to automate the display of the image next to the correct node of the tree. I can provide an image file with an example.

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 Nexus-format tree and performing phylogenetic analyses, tree

Take a look at lmekin() in the coxme package. The motivating data set for my development of coxme was the Minnesota Family Breast Cancer project: 24050 subjects in 462 families. The random effect is an intercept per subject with sigma^2 K as its variance where K is the kinship matrix (1 for self-self, .5 for parent-child or sib-sib, .25 for uncle-neice, etc). lmekin is a linear models front

Dear all, I would like to ask you the following: I have data about different manuscripts, together with data about the presence/absence of copying errors, in the days when manuscript were really manuscripts. I would ideally like to use the data to draw a phylogenetic tree, so that I can infer which ms was copied from which. The error presence/absence is coded in binary format. The plan is to use

Hello R users, Can any one please help me to find a way to build phylogenetic tree by R program from any distance matrix. Suppose I have a data like : MATRIX [1] '1' 0.0 [2] '2' 0.071 0.0 [3] '3' 0.036 0.286 0.0 [4] '4' 0.429 0.75 0.714 0.0 [5] '5' 0.679 0.179 0.214 0.536 0.0 [6] '6' 0.893 0.929 0.964 0.464 0.357 0.0 [7]

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

Hello, Is it possible to include information about phylogenetic relatedness among species (when species are replicates for each study within a meta-analysis) in a meta-anlaysis in the metafor package? Alternatively, I wonder if the method f Lajeunesse 2009 American Naturalist has been adopted in R in any fashion? Thanks, Scott Chamberlain [[alternative HTML version deleted]]

Hello, My name is Sivan and I am a master degree student in statistics,my problem is as follows: I have a dataset containing gene sequences and I would like to create a phylogenetic tree from it. The problem that I can't seem to find a function to do this kind of operation. I read the ape package manual and I haven't found a command that takes raw data and turns it into a tree. does anyone

Hi all, I want to calculate distances between phylogenetic trees. I found functions for symmetric difference (e.g. in ape and in some other packages). In addition to this I also want to calculate quartets and nearest neighbor interchange distances; are there any functions for this? My apologies if they exist and I overlooked. best regards

Hi, I have reconstructed ancestral character states on a phylogeny using MuSSE in the diversitree package and plotted the character state probabilities as pie charts on the nodes. I would, however, like to colour the character states of my extant species, i.e. the tip labels, the same colours as my pie charts, such that all species in state 1 are e.g. blue, species in state 2 red and species in
