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).

residuals from pcaiv
Dear R users,
How can I extract the residuals from a pcaiv/rda in ade4?
In Vegan there is the
residuals()
function, giving the approximation of the original data from the
unconstrained ordination
Is there something similar in ade4?

principal component analysis for class variables
Dear Forum,
I have a class variable 1 (populations A-E), and two other class variables,
variable 2 and variable 3. What I want is to see if the combination of var 2
and var 3, will give me a pattern that allows to distinguish populations.
I found several packages like ade4, with pcaiv function and factoMineR. but
there are not working. Using the ade4 package, when I try to build the pca:

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:

Problemas instalando el paquete "ade4"

Les escribo porque tengo una duda que no he podido resolver por mis

está relacionado con una librería.

Significance of Principal Coordinates
Dear all,
I was looking for methods in R that allow assessing the number of
significant principal coordinates. Unfortunatly I was not very
successful. I expanded my search to the web and Current Contents,
however, the information I found is very limited.
Therefore, I tried to write code for doing a randomization. I would
highly appriciate if somebody could comment on the following approach.

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.

About ade4 and overlaying points
Dear R-users,
Is there an easy way to avoid points one upon another when ploting rows
and columns of 'dudi' objects ? Maybe there is a function in ade4 or in
an other package, or maybe someone has his or her own function to do
this (for example to automatically modify a little the coordinates of
these points to get a readable plot ?).
Thanks in advance.
Best regards,

plot de un cca realizado con Ade4
Un saludo a todos.
Estoy haciendo un ACC y utilizo el paquete Ade4. Cuando quiero realizar un plot del resultado utilizo plot(). el resultado son 6 gráficos: loadings, correlation, inertia axes, scores and predictions, eigenvalues y species. Lo que quería saber es cómo representar en una sola ventana (los 6 gráficos a parecen en la misma) el gráfico correspondiente a Species.
Gracias por vuestra
