Hello all! R2.0.1, W2k. All packages updated.
Iīm heavily dependant on using mixed models. Up tilīnow I have used lme() from nlme as I have been told to. Together with estimable() from gmodels it works smooth. I also often run Rcmdr, mostly for quick graphics. After using Rcmdr, on reopening the R workspace all help libraries for Rcmdr (22 !) loads, among them nlme, but not Rcmdr itself. Why? Now I saw on the list yesterday, that lmer() from lme4 offers better coding possibilities for crossed random factors, it feels natural to switch from lme() to lmer() if estimable() still works on the objects. So I installed lme4, but got a conflict with the (auto)loaded nlme: > library(lme4) Loading required package: Matrix Loading required package: latticeExtra Error in fun(...) : Package lme4 conflicts with package nlme. To attach lme4 you must restart R without package nlme. Error: .onLoad failed in loadNamespace for 'lme4' Error in library(lme4) : package/namespace load failed for 'lme4' Several questions here: Why do all these packages autoload, and could I avoid this in some way? Why a conflict? Isnīt it possible to mask the conflicting parts of nlme when loading lme4? Why are the mixed models tools from the same author(s?) splitted between nlme and lme4? Are there any technical reasons not to include lmer() in nlme? Cheers /CG CG Pettersson, MSci, PhD Stud. Swedish University of Agricultural Sciences Dep. of Ecology and Crop Production.
