Hola buenas. al final corri el siguiente código en mi máquina de casa. El problema es que ha habido algún cambio en la librería lme4, que hace incompatible los nuevos objetos lmer con la funcioón pamer.fnc. En este tipo de situaciones imagino que lo propio sería ponerme en contacto con el autor o intentar corregir yo mismo el código o incluso ambas. ¿Es decortes escribir al autor reportandole el

Hello, I'm using range do define boundaries for a linear model, so the line I graph is only graphed for the range of data. There are NAs in the data, but I dont remember this being a problem before. I typed na.action=na.omit anyway, which has usually solved any NA issues in the past. Any idea why R cant do vector functions for these data? Solution? Thanks, Colin Wahl M.S. Biology candidate

Hi Everyone: It turns out that there's still a small ( I hope ) problem. I'm close but that only counts in horse shoes and hand grenades. Here's my problem: When trying to load a package that I am writing, the load is looking for the packageDescription function in the utils package but not finding the utils package. I looked on cran and utils is not there which makes me think that it

Hello, I'm training a set of data with Caret package using an elastic net (glmnet). Most of the time train works ok, but when the data set grows in size I get the following error: Error en { : task 1 failed - "arguments imply differing number of rows: 9, 10" and several warnings like this one: 1: In eval(expr, envir, enclos) : model fit failed for Resample01 My call to train

Estimado Javier Villacampa Gonzáles Si una persona se toma el trabajo de desarrollar y compartir, como es el caso de R, seguramente conoce de problemas que tuvo que decidir mientras escibía el código, y estará agradecido porque hay gente que utiliza su aporte, su trabajo no fué a la nada, todo lo contrario. En mi caso un solo autor tuvo una respuesta negativa para con migo. Javier Marcuzzi

Dear list, I have found an unusual behavior and would like to check if it is a possible bug, and if updating R would fix it. I am not sure if should post it in this mail list but I don't where is R bug tracker. The only mention I found that might relate to this is "If times is a computed quantity it is prudent to add a small fuzz." in rep() help, but not sure if it is related to

We have released to CRAN a new version of the (recommended) package Matrix, and of package lme4 yesterday. Anyone who gets the new version of Matrix *MUST* re-install lme4 -- if (s)he is using lme4 at all. Technical details about that further below. The fact that yesterday's version number of Matrix is 0.9995875-2, indicates that Matrix' version is indeed approaching 1.0 (*), and

Hi, when calling help.start() I get the message "> sh: firefox: command not found" and the help system is inaccessible (which is an absolute nuisance, but bypassable under http://stat.ethz.ch/R-manual/R-patched/library/) I have no idea what is broken in my system and I didn'n find any pointer in the archives(my search skills may be deficient..)

While running a long script which source()s other scripts I get the following warning: Warning message: In t(object$S[[1]]) : bytecode version mismatch; using eval I cannot replicate it if I run the sourced files line by line though... What is that error? And do I care about it? It doesn't seem to affect my output as far as I can tell. Thanks! Justin > sessionInfo() R version

Hi, For some reason do.call on anova fails if the models are named lmer objects. Consider the following example: library(lme4) models <- list( lmer(Reaction ~ Days + (1| Subject), sleepstudy), lmer(Reaction ~ Days + (Days | Subject), sleepstudy)) # # models is an unnamed list, do.call works (although with warning): do.call(anova, models) # # after labeling the models, do.call gives an

Dear Fellow R Users, I am having a problem with the Matrix package, in Windows XP on R 2.15.1 . This is the only package where I experience this. I remove the package first, re install, and then when trying to load, get a LoadLibrary failure as below. Thanks in advance for any assistance.

Dear all, how can I use vcovHC() to get robust/corrected standard errors from an arima() output? I ran an arima model with AR(1) and got the estimate, se, zvalue and p-value using coeftest(arima.output). However, I cannot use vcovHC(arima.output) to get corrected standard errors. It seems vcovHC works only with lm and plm objects? Is there another way I can get robust/corrected

Javier, Creo que aquí aplica la ley de Linus que dice: "Dado un número suficientemente elevado de ojos, todos los errores se convierten en obvios". La persona que revisa y encuentra un error no necesariamente tiene que ser la misma que la que lo escribe. Una motivación muy importante al compartir un código es la de recibir los beneficios del control de calidad por parte de tus pares.
