rda variance partioning in vegan problems
...heir unique and
binary interactive variance, I run the ~30 conditioned RDAs necessary to
determine the "pure effects" of each group and the "pure binary
interactions" of those groups with each other.
My method for partitioning the variance of binary interactions is as
follows:
Inertia of the interaction of water chemistry and geography = inertia of the
combined effect (conditioned on the remaining groups) - Inertia of just
Waterchemistry - inertia of just geography.
When I do this for each combination two problems arise:
1. I get small negative numbers when 0 should be the low...

Total inertia in package Vegan?
Dear all at the R-project help list.
I have run into a problem when it comes to getting values for "total inertia" and "R-squared" for my DCA using "decorana" in the package "vegan". I have tried the "goodness" function, but the reply indicates that it does not work with "decorana" class objects. In Canoco one gets the Total inertia in the output together...

lua assist
Hello,
For Lua inclusion in Syslinux an idea to ship with an com32/lua/assist
directory and an com32/lua/patches directory.
In the patches directory patches against a pristine lua tarball
and the assist dir contains scripts for further tayloring.
This is what I have in mind:
| milleune at inertia:~
| $ git clone http://www.stappers.it/tracking/syslinux/.git syslinux-lua-stappers

Encontrar las variables más importantes en componentes principales
Hola compañeros de la lista. Qué tal.
Tengo un análisis de componentes principales, en el que se evalúan
aproximadamente 1000 variables. Usando la función dudi.pca e
inertia.dudi obtengo una cantidad de información sobre la influencia de
las variables sobre los dos componentes principales. Me gustaría saber
si existe alguna función que sobre esta información me arrojara la lista
de cuáles son las variables que más influyen sobre el resultado.

How do I get "total inertia"+"R-squared" in R?
...to solve the problem.
I have put in my data R, using the "decorana" function in the package "vegan" and received nice coordinates for the DCA of sites and species, as well as the Eigenvalues for the four axes.
My problem is that I can not figure out how to get the "Total inertia", or the "R-squared" value. I thought that I could solve this problem by using the "goodness" function, but then receives the message
"Error in UseMethod("goodness") :
no applicable method for 'goodness' applied to an object of class "summary...

The RV coinertia coefficient to interpret multivariate analysis plots
Dear all community,
My issue is related to the R package (made4) that permits me to calculate
the RV coefficient of co-inertia. However, it is a theoretical question.
And if I am not mistaken, the list Usenet groups sci.stat.consult is not
currently active.
Let me explain briefly:
Through different microbiota datasets, I have plotted PCoA, db-RDA and
sPLS-DA using 3 different types of normalization methods (Total sum of...

Cummulative Variance in Correspondence Analysis (ADE4)
Hi all:
How can I calculate the cumulative variance (or variance for each component)
in correspondence analysis?
If were possible in ADE4 package
Thank you

Kickstarting several *different* setups
...stomize them
Seconded.
Personally, I recommend either ansible or bcfg2 over other tools.
Puppet has a larger user base, but when I talk to users at conferences
(such as LISA), ansible and bcfg2 users tend to like their tools, while
an awful lot of people dislike Puppet but use it anyway due to inertia.

calculation of inertial difference with huygens theorem in ward clustering ?
Hello to the R people,
within ward clustering the distance calculated to decide the clustering
of 2 subsets (h1 and h2) is the variation of inertia :
d(h1,h2)=I(h1Uh2)-I(h1)-I(h2);
i've been said that a way to calculate faster this d(h1,h2) is using the
huygens theorem decomposing the inertia into "the inertia to the
centroid + the distance to an axe" (that's my version ...). My problem
is that i don't really see how to s...

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 ayuda.

Winbind backend : rid is too much underappreciated
I just came to the conclusion that the rid backend has been very much underappreciated. Too much mental inertia about how things used to be made?
