Dear All: We have been experiencing networking issues so I don't know if this got through; I can't see it in the archive. My sincere apologies if this appears twice. I may have found an unusual bug and am posting here to see if anyone can reproduce it on their system. First of all, sessionInfo(): > sessionInfo() R version 2.7.1 (2008-06-23) i386-apple-darwin8.10.1 locale:

Gracias, Javier. Los datos "d" corresponden un archivo de texto de ~1.92GB. Voy a explorar la posibilidad con sqldf, aunque confieso que mi conocimiento de SQL es bastante limitado.

Hola, ¿qué tal? Pido excusas primero a aquellos a quienes el tema le resulte geográfica y materialmente ajeno. Estos días se ha hablado de la nueva Ley de Transparencia española que tiene que ver con la obligación de las administraciones públicas de ceder sus datos a los ciudadanos. En los medios de comunicación se ha enfocado desde un punto de vista del control de la gestión de los políticos.

Estimados Reailizo una pregunta general, casi desconociendo. Se me ocurrió explorar lo siguiente: hay ejemplos de programación lineal o utilizando la herramienta solver de excel, donde se realizan algunos cálculos, lo más sencillo de comprender y documentado (todos lados) es una cantidad de productos, un costo de compra, un costo de venta, una cantidad para invertir y ¿cuánto me conviene

Hola, Otra forma, quizás algo más rápida, especialmente para unos conjuntos tan grandes, que la de sqldf es "data.table": library(data.table) x <- 1:3 y <- 4:6 d <- data.table(x, y) d[,z := paste(x,"-",y,sep="")] > d x y z 1: 1 4 1-4 2: 2 5 2-5 3: 3 6 3-6 Y bueno, "dplyr" también es otra opción muy rápida... También, y recuerdo que hace

Buenas noches, tengo dos vectores con nombres. El primero es largo, nombreL, y el segundo corto, nombreC. Quiero contar cuantas veces aparece alguno de los nombres del vector corto en el largo. Lo que estoy haciendo es lo siguiente: cuenta <- 0 topL <- length(nombreL) topC <- length(nombreC) for (i in 1:topL) { for (j in 1:topC) {

Acudo a su conocimiento apara obtener ayuda Se tiene un gráfico como el que les adjunto, es un gráfico de un instrumento meteorológico el cual registra información de un día, se quiere hallar el valor en el corte de la gráfica y la vertical Horaria (8 , 9, 10, ...) el cual se registra como valor de la obserbacion, despues debo realizar analisis estadistico.

Hi, I was recently plowing through the docs of the quantreg package by Roger Koenker and came across the total variation penalty approach to 1-dimensional spline fitting. I googled around a bit and have found some papers originated in the image processing community, but (apart from Roger's papers) no paper that would discuss its statistical aspects. I have a couple of questions in this

Hola a todos, Simplemente comentar que me tengo encontrado con muchos problemas de optimización. Mi recomendación general, en el caso multidimensional y si el tiempo de computación es importante, sería buscar un algoritmo diseñado para el tipo de problema (evitar los algoritmos más generales tipo optim si puede haber problemas de mínimos locales). Algunos casos que tengo resuelto con R

Dear R-list, I am wondering how to perform a bootstrap in R for the weighted time dependent Cox model? (Andersen?Gill format, with multiple observations from each patients) to obtain the bootstrap standard error of the treatment effect. Below is an example dataset. Would 'censboot' be appropriate to use in this context? Any suggestions/references/direction to R-package will be highly

Hi, every body! I am a new comer for R, so my question would unavoidablely sounds stupid. Sorry! In my experiment, there are two type of soil ( soil F and soil D), each half of them were subjected to steam sterilize (result in FS and DS soil). A equal volume of soil from two of the four soil types (F, D, FS, DS) were mixed as follows: F+F, F+D, F+FS, F+DS, D+F, D+FS, D+DS, FS+DS (eight

Hello all, I am trying to understand the different results I am getting from the following 3 commands: chisq.test(c(62,50), p = c(0.512,1-0.512), correct = F) # p-value = 0.3788 binom.test(x=62,n=112, p= 0.512) # p-value = 0.3961 2*(1-pbinom(62,112, .512)) # p-value = 0.329 Well, the binom.test was supposed to be "exact" and give the same results as the pbinom, while the chisq.test

Dear all, I need to understand a thing in the beheaviour of the two functions aov and anova in the following case involving an analysis of ANOVA with repeated measures: If I use the folowing command I don´t get any problem: >aov1 = aov(response ~ stimulus*condition + Error(subject/(stimulus*condition)), >data=scrd) > summary(aov1) Instead if I try to fit the same model for the

Hi All , Can anybody tell me if there's any way to get the summarized anova values.Now i will explain what i mean , when i say "*summarized*". Below you can see the anova table of recmeanC1 with rest* all* i.e from recmeanC2 to i15(predictors),as shown in table. Df Sum Squares Mean Square F value Significance [Pr(>F)] recmeanC2 1 89.272 89.272

Buenas tardes chicos, estoy intentando hacer un gráfico que resuma para cada dia de la semana la información de algunos distritos específicos de los que contiene mi variable, ejecuto esta sintaxis pero me da un error Error: Mapping should be created with `aes() or `aes_()`. Alguien me puede orientar sobre que estoy haciendo mal, llevo mucho rato atascada. Muchas gracias df_nuevofinal %>%
