Hello I want to batch job the calculation of many GLM-models, extract some values and store them in a file. Almost everything in the script below works (read file, extract values and write them to file) except I fail in indexing the GLM with the modelstructure it should run. Running GLM's conventionally is no problem. Conventionally a GLM is calculated as:

Dear all, I'm pleased to announce the release on CRAN of the "mmand" package (for Mathematical Morphology in Any Number of Dimensions). It provides functions for performing mathematical morphology (erode, dilate, etc.), smoothing, and other kernel-based operations on array-like objects of any dimensionality. The package is centred around a flexible function called morph(), which can

Dear all, I have just uploaded 4 new packages on CRAN, which are on the long term designed to replace the "old" package adehabitat: * adehabitatMA: functions to perform spatial operations (morphology, buffer, etc.) * adehabitatHS: functions for the analysis of habitat selection by wildlife * adehabitatHR: functions for home range estimation of animals * adehabitatLT: functions for

Fellow R Users: I'm not extremely familiar with lda or R programming, but a recent editorial review of a manuscript submission has prompted a crash cousre. I am on this forum hoping I could solicit some much needed advice for deriving a classification equation. I have used three basic measurements in lda to predict two groups: male and female. I have a working model, low Wilk's lambda,

Dear R-users, I've been reading a bunch of things on linear models but cannot quite find a clear answer. How can one determine whether a linear model is significant or not? For background info, I am modelling the response of topographic slope to the distance of a catchment's outlet. Some guys have shown that if there is a significant fit to a linear model, one can deduce the dynamic

Hi, I just imported two raster maps into R using the SPGRASS6 package, one containing elevation data and the other containing an erosion index: Kar_inc <-readRAST6("Incis_Kar", plugin=FALSE) Kar_dem <- readRAST6("DEM_Kar", plugin=FALSE) I just wanted to make a xy plot of erosion parameter vs elevation. How does this work? I don't get how to handle

Hello, all. I'm investigating the rate at which skeletal joint surfaces pass through a series of ordered stages (changes in morphology). Current statistical methods in this type of research use various logit or probit regression techniques (e.g., proportional odds logit/probit, forward/backward continuation ratio, or restricted/unrestricted cumulative probit). Data typically include the

Hi all, I'm a newbee using R. I need to do a classification tree using the rpart package. Basically I have a set of birds of known sex and several morphological measurements and we want to predict the sex using the morphology. I read my csv file and it shows up in R no problem, looks fine but when I execute the following rpart command

Hi everyone, I?m a student and relatively new to R so apologies in advance if this question seems stupid or obvious to you. I have collected a dataset with about 60 species of diatoms (count data from 19 different sample sites) and environmental variables for each site (salinity, pH, etc.). It?s all in the same dataset but distinct in R through the functions below diat <- diatom [, 1:60]

Hi, I've been following the changes in LLD's software architecture. Recently a new file was added: Alias.h In this file, the curret Atom set is extended with an AliasAtom. While the change seems innocent enough, it has some nasty potential. Simple.h and Alias.h are placed in the ReaderWriter component. This is the 2nd component in the layering: Driver ReaderWriter Passes Core The problem

Buenas a todos, relato directamente mi problema. Estoy preparando unos datos para ingresarlos en otro programa que requiere una columna de ID y el resto de la información toda seguida sin espacios. El echo es que yo tengo la información separada en columnas, por ejemplo: ID col2 col3 col4 col5 etc. y precisaría dejarla de la siguiente forma: ID col2col3col4col5 etc. Para luego escribir a

Hi, I'm trying to do a non-metric multidimensional scaling using isoMDS. However, I have some '0' distances in my data, and I'm not sure how to deal with them. I'd rather not drop rows from the original data, as I am comparing several datasets (morphology and molecular data) for the same individuals, and it's interesting to see how much morphological variation can be

Hello. I'm interested in creating a Hebrew stemmer to use with Xapian. Hebrew is a complicated language to stem, as it uses the semitic "root" system, rather than prefixes and suffixes, and has many irregularities in accidence (morphology). Fortunately, two bright fellows from the Technion University in Israel have already created a Hebrew morphological analyzer as part of their

The inverted dependency of Core to ReaderWriter via Simple.h was already present. My idea was to fix the problem before it gets bigger. My proposal would be to move Simple.h and Alias.h to Core. Similar to UndefinedAtom.h etc. It would be even nicer to make the naming consistent as well, since there already is UndefinedAtom.h SharedLibaryAtom.h etc Maybe: SimpleAtom.h AliasAtom.h Moving the file
