AMOVA error: 'bin' must be numeric or a factor
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:

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

ade4 package update
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

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.

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

New package : ade4
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.

New package 'ade4TkGUI', a Tcl/Tk GUI for ade4
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).

R for copying and pasting selected image files?
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

nested if/else very slow, more efficient ways?
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

removing a specific number of digist from a character string
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,

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.
