This is not a request for coding help so there is no reproducible code, rather I am trying to figure out if anyone had had a similar experience. My question is related to partitioning the variance in rda (vegan) results for multiple groups of variables. I have a high dimensional dataset with 79 explanatory variables and 9 response variables. Within those 79 explanatory variables there are ~8

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

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 | milleune at

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

Dear people at the R-help-list. I have run into a problem in the package "vegan", while using the function "vegan", and would greatly appreciate any advice how 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

I am getting the following erro rmessage in ordistep. I have a number of similarly structured datasets using ordistep in a loop, and the message only occurs for some of the datasets. I cannot include a reproducible sample - the specific datasets where this is occur ing are fairly large and there are several pcnm's in the rhs of the formula. thanks for any pointers that may allow me to

Hola Argel, Puedes encontrar un par de ejemplos que cómo conseguir una valoración (qualitativa y cuantitativa) de la contribución de cada variable a cada componente principal, en el libro "Exploratory Multivariate Analysis by Example Using R". Este libro está basado en la librería "FactoMineR". Los ejemplos están en el capítulo primero. No he mirado como se haría esto con

Hello Sir I am getting problem in plotting in CCA . Could you please help me? I wrote the below command but I don't know why it is taking only first 5 env data rather than all 9. > strain.data <- read.xlsx("Dee rhiz.xlsx", sheetName="strain", header = T, row.names = 1) > env.data <- read.xlsx("Dee rhiz.xlsx", sheetName="env", header = T,

Hola! No he podido consultar la doc. del paquete ade4, algo debe estar caído en CRAN ahora mismo. Dos cosas sobre la metodología -aun desconociendo los detalles de cómo lo hace ade4: El output de un PCA, los "pesos" de cada variable en las dimensiones de los componentes se interpretan como correlaciones, a mayor valor absoluto mayor asociación variable-componente. Ahora, como tales

Hi all: How can I calculate the cumulative variance (or variance for each component) in correspondence analysis?

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

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

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

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? After strugling for two days to configure a member server against a Samba Active Directory with the ad/RFC2307 backend, I turned to the rid backend and voil?! all my problems are gone. Having to manually edit uids/gids in UNIX Attributes under RSAT

This release restores wheel emulation on absolute devices and drops the forced direction locking for scroll buildup during wheel emulation since it made it almost impossible to actually scroll in both directions. Since horizontal scrolling is disabled by default anyway, we don't need this lock. Peter Hutterer (5): man: add a warning that wheel emu inertia must be set and it isn't

I'm working with capscale and permutest for the first time, and having trouble getting statistical analyses for more than one constraining variable. I've read the documentation, but setting first=FALSE or using by="axis" doesn't seem to be helping. capscale seems to be fine, I receive output for more than one constrained axis. What am I doing wrong?

We need to keep the discussion on the list. When I run your code, there are several problems. strain.data <- read.xlsx("Dee rhiz.xlsx", sheetName ="strain", header = T, row.names = 1) str(strain.data) # lists 9 columns at the end with all NAs strain.data1 <- (strain.data, sqrt.dist = TRUE) # this is not a valid R line. I get Error: unexpected ',' in

This is a general statistics question so I'm sorry if its outside the field of r help. Anyway, I have a suite of female and male traits and I have made a matrix of correlation coefficients using rcorr(). This results in a 6 by 6 matrix like this..
