When I try to run the example from Variogram with an lme object, I get an error (although summary works): R : Copyright 2005, The R Foundation for Statistical Computing Version 2.2.1 (2005-12-20 r36812) ISBN 3-900051-07-0 ... > fm1 <- lme(weight ~ Time * Diet, BodyWeight, ~ Time | Rat) Error: couldn't find function "lme" > Variogram(fm1, form = ~ Time | Rat, nint = 10, robust = TRUE) Error: couldn't find function "Variogram" > library(nlme) > fm1 <- lme(weight ~ Time * Diet, BodyWeight, ~ Time | Rat) > Variogram...

Dear R-help, The following nlme example, from help(Variogram.gls), does not work on my system. > data(BodyWeight) > fm1 <- gls(weight ~ Time * Diet, BodyWeight) > Variogram(fm1, form = ~ Time | Rat)[1:10,] Error in FUN(X[[1]], ...) : unused argument(s) (method ...) It looks like I might not have loaded a necessary package. I did load nls and lattice (the latter not actually being listed in the pack...

Hello, I am new to R and have a couple of questions. My data set contains the variables "Bwt" and "Hwt", which are bodyweight and heartweight, respectively, of a group of cats. With the following code, I am making two plots, both to be viewed in the same plot window in R: library(MASS) maleData <- subset(cats, Sex == "M") linreg0 <- lm(maleData$Hwt ~ maleData$Bwt) par(mfrow=c(1,2)) plot(maleData$Hwt ~...

...hat that the df in the table below are not correct. Time should have df=157 if it were to agree with P&B (2000) text. ) I see that Ron has now cross-posted to R-SIG-ME, so if you address this to that group I will see it. My check with lmer: (fm1BW.lmer <- lmer(weight~Time*Diet+(Time|Rat), BodyWeight)) (fm1BW.lmer <- lmer(weight~Time*Diet+(Time|Rat)+(Diet|Rat), BodyWeight)) I'm very open to corrections on the model construction. The Time and Diet estimates are the same although the std-errors are different for Diet. --David. > > As an example I use "Pinheiro, J. C. & Ba...

I'm looking at Pinheiro & Bates "Mixed-Effects Models in S and S-PLUS" at the moment. Several datasets are used, one of which is called "PBIB" (a partially balanced incomplete block design). All the other datasets can be found somewhere or other in R. However, I cannot locate PBIB, and it does not seem to be mentioned in the latest edition of the R Full Reference

  Hola,   Por favor, ¿podríais indicarme qué recursos (librerías o ideas) pueden resultar de utilidad para crear un gráfico del estilo del de la figura 3.8 del siguiente link?   http://www.tsc.uvigo.es/BIO/Bioing/ChrLDoc3.html#3.5   Actualmente estoy utilizando funciones muy básicas y la verdad es que no me encuentro muy satisfecha con el resultado.   Muchas gracias.   Eva [[alternative HTML
