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

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

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

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]]

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

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]

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

Hello, I am trying to import a phylogenetic tree from Mesquite into R. When I use the read.nexus command I get the following message: Warning message: In matrix(x, ncol = 2, byrow = TRUE) : data length [589] is not a sub-multiple or multiple of the number of rows [295] A phylo object is created but I am unable to plot it (when I try R freezes) and I can tell by looking at the tip labels that

friends, I need some tool to visualize the results of hierarchical clustering. Specifically, I want to plot it as a radial plot as a phylogenetic tree. In addition, I want to specify the color to each leaf node. I search all phylogenetic tree plotting routines here, they all cannot show the leaf nodes and their colors. Since i will have a lot of leaf nodes, the color needs to be specified and

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

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

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 all, I have been receiving the error "tree connect failed: ERRSRV - ERRinvnetname (Invalid network name in tree connect.)" for a while and I finally fixed it, but I have some questions about why it was happening. Firstly, it is Samba 2.0.7 running on Mandrake 8.0. My smb.conf file is at the end of this message. The machine's name is pinhead and in checking log.pinhead, I

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, Hua

Hello, I would like to place shaded boxes on different areas of a phylogenetic tree plot. Since I can not determine how to find axes on the phylogenetic tree plot I am not able to place the box over certain areas. Below is example code for the shaded box that I have tried to use, and the first four values specify the position. rect(110, 400, 135, 450, col="grey",

Dear R-helpers and Klaus, I would like to know how to write out a tree file with bootstrap from phangorn package. That tree file could be in newick format or others. I am new for phylogenetic operation in R. Could you please give me any directions on that? Thanks in advance. Best wishes, Jian-Feng, ######## # as a example # I accomplished 1000 bootstrap simulation on a fit object (a maximum

Hello, I'm using Text::MultiMarkdown in my website, and I would like to know if there is any way to get syntax highlighting in code blocks. Thanks, -Mike Doherty

Hello, my name is Ikey Doherty. I am the founder of the SolusOS Linux Distribution. With SolusOS 2 we have decided to create our own base from scratch, using the PiSi package manager. After many repository revisions, it soon become apparant that GCC (4.7.2 in this instance) is dog-slow. Out of pure curiosity I attempted to rebuild packages using Clang. Clang had been pulled in as a dependency
