Dear All, A few weeks ago I posted a question to this list but unfortunately got no answer! A friend warned me of my english. Again, the problem is: A 2-level 5-factors completely randomized design was used to investigate the potential effects of those factors on a solution's characters (several response variables). Each response-variable was measured repeatedly (13 times) during a 30-day period. We are insterested in studying each response at-a-time. Is there a R-package suitable for this kind of analysis? Thanks, Eduardo Esteves
I don't remember your original post, but I doubt if the nonresponse was due to the quality of the English prose; English is a second language for a substantial porportion of the people who subscribe to this list, and most of the rest of us are sensitive to that issue and appreciate any efforts to meet us in English. Have you studiend the posting guide at "R-project.org/posting-guide.html"? I'm guessing that you may want "lme" in library(nlme), described by Pinhiero and Bates (2000) Mixed-Effects Models in S and S-Plus (Springer). hope this helps. spencer graves eesteves at ualg.pt wrote:>Dear All, > >A few weeks ago I posted a question to this list but unfortunately got no >answer!

[R] help repeated measures factoial design
If you are interested in study each response isolated and because you have a temporal time-series it could be a possibility for your study to modelize that time-serie with ARMA or GARCH process. For that you have ts and tseries packages. Palhoto.> > Dear All, > > A few weeks ago I posted a question to this list but unfortunately got no > answer!
