Hi: Where is the iris data set actually located in the R 2.1.0 folder (under W XP)? Is it a text file or it is a binary file? Ruben

Hi, I'm trying to figure out how to use lme() for analyzing a split-plot experiment. I've been looking at the examples from the 'R Book', those are nested but with only one factor at the whole-plot level, my test is 2^2 at the whole-plot level, with a single many level factor at the sub-plot level. My question is about properly specifying the random effects part of the model,

Does anyone know of a package to make a map from GIS data, and/or would it be easier in one of the free GIS programs. I would like to make a map of the savannah river area with our sampling locations. thanks stephen -- Let's not spend our time and resources thinking about things that are so little or so large that all they really do for us is puff us up and make us feel like gods.

Dear R Helpers, I have attempted "optim" function to solve a two-dimensional optimization problem. It took around 25 second to complete the procedure. However, I want to reduce the computation time: less than 7 second. Is there any optimization function in R which is very rapid?

DeaR ComRades, This is a quote from a News article in Science's 11-February issue, about competitions to model data: "For Chris Raimondi, a search-engine expert based in Baltimore, Maryland, and winner of the HIV-treatment competition, the Kaggle contest motivated him to hone his skills in a newly learned computer language called R, which he used to encode the winning data model.

Hi: I need to plot two time series in the same plot and they cover the same time range and have the same frequency. With RSiteSearch("multiple series plot") i found this post by Gabor Grothendieck: http://finzi.psych.upenn.edu/R/Rhelp02a/archive/42281.html Exactly what i need except for one detail. I want one series to be made of points and the other by a line. When I simply try: xts

Hola, ¿qué tal? Me han pedido que genere unos gráficos para insertarlos en un docuemento de Word. Yo suelo generar gráficas en formato PNG, pero me han dicho que "quedan mal". Y yo apenas sé nada de Word. ¿Cuál sería el formato gráfico más adecuado en este caso? Un saludo y muchas gracias, Carlos J. Gil Bellosta http://www.datanalytics.com

Hi R-listers, I have developed 47 GLM models with different combinations of interactions from 1 variable to 5 variables. I have manually made each model separately and put them into individual tables (organized by the number of variables) showing the AIC score. I want to compare all of these models. 1) What is the best way to compare various models with unique combinations and different number

Hola. Tengo un archivo de texto con formato Ansi en Windows que lo quiero convertir en una serie temporal pero cuando lo trato de hacer con el siguiente comando: out <- read.zoo(readLines(con <- file("log2.log", encoding="UCS-2LE")),FUN = as.chron) Me da los siguientes errores: Error en file(file, "rt") : no se puede abrir la conexión Además: Mensajes de

Hi R people: I am new to R. I am writing a function to (1) produce a sparse stochastic Gaussian 2D field and (2) perform a systematic transect sampling on this field, this carried out many times in a simulation framework. My function does a good job at producing the random field (a matrix of zeros and some manifestations of the stochastic process, depending on a parameter of the function

ComRades: I have a glm where interest lies in the estimated mean levels of the response Y for every level of factor Year (regardeless of statistical significance of the factor), when the effect of other factors have been accounted for. The model is of the form: fit<-glm(Y~Year+Mo+Area+Ship+Eff,family=gaussian(link="log"),data=data) where Year is categorical and has T levels

Greetings comRades: Has anyone worked out a procedure to calculate the estimated covariance between the beta and lambda estimates in the likelihood-based geostatistical model implemented in package geoR? If so, please help me out by letting me know. Do I have reasons to expect that this covariance term would be big or perhaps more happily, that it could be discarded without much effect?
