Was there ever an answer to this question about how to do amova with factorial data? t hundley [[alternative HTML version deleted]]

Hi! I am trying to analyse my data using amova (http://www.oga-lab.net/RGM2/func.php?rd_id=pegas:amova): My input to R is a DNA sequence file, format=fasta dna<- read.dna("XX.fasta", format="fasta") #left other options as default d<- dist.dna(dna, model="raw") g<- read.table("XXX.design") Load necessary libraries: library(pegas)

Hello, I am interested in using the amova function of ade4 package of R. I would like to know if there is any possibility to perform an amova with a specific anova model, as a factorial anova with some factors nested, or, if this could not be done, how could I perform an anova with my specific model but with molecular distance data? I would be very grateful if you could help me with this fact in

The ade4 package (v. 1.2-1) has been updated on CRAN. New features include: - functions based on Rao's axiomatization of diversity measures : Rao's diversity coefficient and dissimilarity coefficient (divc and disc) - functions based on Excoffier et al. analysis of molecular variance with tests of the difference among the factors (amova). - functions introducing double principal

Hi, I'd like to conduct an amova in R from diploid genotpyic data. The packages pegas and ade4 require a Euclidian distance matrix. Is there a simple method to generate a dist object from genotypic data at the individual level? I think the dist.genet of ade4 only generates distances at the population level. Thanks for any help, Mike. [[alternative HTML version deleted]]

Dear All, I'd like to perform adonis (from the vegan package) rather than amova (in ade4) on some haplotype data, as I have crossed factors. Is there a simple way to tweak the source to allow weights (haplotype frequencies) in a similar way to amova? Best Simon

Hello, The ade4 package is now available on CRAN. ade4 is a multivariate data analysis package oriented towards statistical ecology. The main functions include one-table (PCA, COA, MCA, PCO, etc.), two-tables (PCAIV, Co-inertia, CCA, etc.) and k-tables multivariate analysis methods, with several Monte-Carlo tests and many graphical display methods. A complete documentation with many example data

Un saludo R-inómanos: Les escribo porque tengo una duda que no he podido resolver por mis medios y actuales conocimientos. He querido instalar el paquete "ade4" en R (OP linux-ubuntu) pero no he podido por un error que según entiendo está relacionado con una librería. Me permito mostrarles el texto que me aparece luego de tratar de instalarlo desde los repositorios: >

Dear R-Users, ade4TkGUI is a new package available on CRAN. It implements a Tcl/Tk graphical user interface (GUI) for the ade4 package. Only the most basic functions of ade4 have a GUI in this first version : classical one-table data analysis methods (PCA, COA, MCA, PCO, etc.), one table with groups of rows (BGA, WGA, DA), and two-tables analysis methods (Coinertia analysis, CCA, PCAIV).

Hello, I would like to use R to process a list of text strings. The text strings are filenames, encoding experimental settings. Based on the information in there I'd like to select certain files and copy only the selected files to another directory. The files are images and there is no need, actually no desire, to open them. Is there a way to use R for copying and pasting files with any

Hello, in the data.frame "resultsfuzzy" I would like to replace the characters in the second column ("5a", "5b", ... "5e") with numbers from 1 to 5. The data.frame has 39150 entries. I seems to work on samples that are << nrow(resultsfuzzy) but it takes suspicously long. Do you have any suggestions how to make the character replacing more

Hello, I would like to remove the last 8 digists of character strings in a vector. Below I added a couple of elements from that vector. I have a problem defining a pattern to replace the digits using for example "sub". Removing the ".tif" part works fine using sub('.tif',"",x), but how do I get rid of the four preceding digits? Thanks for your help, Kim

How do I change the postion of the legend in s.value {ade4} from the defaul , bootom left? thanks Nevil Amos

Dear All, I am using the scatter.dudi finction in the 'ade4' package to produce correspondence analysis (nice) plots. I do not seem to figure out how to plot the raw coordinates only -- or column coordinates only. I would appreciate any help in doing that. Here is the example I am following -- from the package. data(banque) > banque.acm <- dudi.acm(banque, scann = FALSE, nf =
