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&qu...

Hello, I am trying to run some AMOVA analyses with the amova function in the package ade4. When running the example dataset provided in ade4, I noticed a difference between the published results from the same data (Excoffier et al. 1992) and what ade4 calculates. Below are the data for "within sample/population" from ad...

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

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 wou...

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

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,...

...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 coordinate analysis (dpcoa). - genet class and related functions to analyse genetic data (tables with populations in rows and alleles/loci in columns). - kdist class and related functions to analyse series of distance matrices measured on the same indiv...
