similar to: hc2Newick is different than th hclust dendrogram

Dear R-helpers, I would like to export hierarchical clusters e.g. fit <- hclust(d, method="ward") in the newick format write(hc2Newick(fit),file='hclust.newick') Searching for a possibility I found this solution in the package ctc (http://www.bioconductor.org/packages/bioc/html/ctc.html). However, neither from this site nor via CRAN it is possible to install the package.

Hi, I'm doing hierarchical clustering, and want to export my dendrogram to a tree-viewing/editing software. I can do this by converting the data to Newick format (hc2Newick in ctc package), but I can't get branch lengths to show in the resulting phylogram. I figured it might help to convert my hclust object into a phylo object (as.phylo in ape package), but the following lines give me

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

I am having trouble displaying a dendrogram of evolutionary relationships (a phylogram imported from the ape package) as the vertical component of a heatmap, but keeping the hierarchical clustering of the horizontal component. The relationships of the vertical component in the generated heatmap are not that of the dendrogram, although the ordering is. In more detail, I am attempting to generate

Hi, I am a beginner for R. I had use gplots to generate a heatmap as following: >heatmap.2(matrix, col=topo.colors(75), dendrogram="column", Rowv=FALSE, trace="none", key=TRUE, keysize=0.8, density.info="none", cexRow=0.2, cexCol=0.6) It work well. It generate heatmap whith rcolumn clustering dendrogram and I can export a very nice graph. But I don not know how

Hi, I have generated a skyline plot of a tree in newick format using "ape". How can I plot the error bars for this graph? I only have the the tree data. un<-"((((8.1:0, 20.1:0):0, 6.1:3):123, (((((35.1:0, (22.1:0, (43.1:1, 29.1:0):0):0):4, 25.1:6):0, ((42.1:0, 21.1:0):3, (39.1:0, 2.1:0):3):1):8, (3.1:0, 7.1:0):8):48, (((((15.1:0, 14.1:0):0, 11.1:0):0, 37.1:0):0,

Hi, I've been investigating the ape package for a while, and I was wondering if it is possible to: - display the names of the internal nodes (from a newick tree) - plot a pie-chart on top of each of the internal branches in a phylogram plot Thanks in advance, Cheers, Albert.

Hi all, I'm on Mac OS X 10.4... So I've got a small python script I need to run from R. However, to get the python script working, I need to have the shell that R calls get settings from my .bash_profile file, which apparently it doesn't currently (the shell R calls uses an older version of python, and also this older version of python can't see various python modules I have

Dear all, Does anyone know how can one loop through the newick phylogenetic trees stored in a nexus file and generate an "average" skyline plot with coalescent intervals? I have managed to generate the plot with one tree, but is it possible to create that "consensus/average" plot in R? tr<-"((((8.1:0, 20.1:0):0, 6.1:3):123, (((((35.1:0, (22.1:0, (43.1:1,

Dear R-helpers, Christoph (author of phyloclim) and Luke (author of tkrplot), I would like to get your helps on installing of phyloclim in Ubuntu linux. It seems a package named 'tkrplot' could not be installed at firstly, then packages depends on it could not be installed latter. As I have tested, installation of phyloclim works smoothly in Mac. I attempted to install these packages in

Ape is an R package for "analyses of phylogenetics and evolution". The first version (0.1) has been released on 27 August 2002 and is available on CRAN. >From the 'Description' file of version 0.1: Ape provides functions for reading, and plotting phylogenetic trees in parenthetic format (standard Newick format), analyses of comparative data in a

Dear all, I'd like to introduce a new R package called *phylogram,* for working with evolutionary trees as deeply-nested lists known as "dendrogram" objects. The package provides functions for importing and exporting phylogenetic trees in the Newick parenthetic text format, as well as several functions for command-line tree manipulation. With an emphasis on speed and computational

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 list, I am trying to plot a radial dendrogram using the ape package, which requires my data to be of class 'phylo'. Currently I have my dendrogram stored as an object of class 'dendrogram' which was produced from an outside bit of C code, but was made into an object of class 'igraph.eigenc' and converted to a dendrogram using 'as.dendrogram()' from the igraph

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

Hi all, I have a table structure with me not having an id column. When I try to delete the row i get an error ''Unknown column "table.id"''. Can i do the action with any other method than destroy/delete? Or with the same method and any other conditions? Thanks. Sainaba. -- Posted via http://www.ruby-forum.com/.

It always helps to check whether you got the data into R correctly. Hint: What does str(credit) tell you?

Is it possible to have a simple table but without using <th> and the long ----- ? Sonja

Appreciate the info, it&rsquo;s good to know.

I had a 2-day lapse in brain function apparently. Discovered that even though UltraEdit-32 says its editing/saving in UNIX mode, it is not 100% true. Ran my new configs through dos2unix and bam...no more error message. Please excuse my previous post (I always seem to do that...) and sorry about the junk. Levi Masterson
