AMOVA results from ade4 different than in the reference publication
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 ade4 and from the haplotypic distance matrix in the paper:

question about amova (ade4)
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

question about capscale (vegan)
Hello, I am interested in using the capscale function of vegan package of R. I already have a dissimilarity matrix and I am intended to use it as 'distance' argument. But then, I don't know what kind of data must be in 'comm' argument. I don't understand what type of data must be referred as 'species scores' and 'community data frame' since my data refer to

adonis, amova and haplotype frequency
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

AMOVA in R
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]]
