Dear all, I've got a big problem. I try to analyse my data using R with a mixed model ANOVA without useful results and success. My data are as follows: 3 factors (Treatment, Site, Subsite) with 'Subsite' as random factor and nested into 'Site'. I want to analyse the effects of the three main effects (factorial design to a specified degrees (2)) with the interactions between 'Treatment x Site' and 'Treatment x Subsite' but without 'Site x Subsite'. I also want to analyse the "magnitude of effects" of all effects Is anybody out there who could help me with the function and the syntax Thanks and cheers!

Try the book Mixed-effects model in S and S-PLus by Pinheiro and Bates. They have pretty good examples of code and analysis techniques to tackle your data.
