Doubt on using lattice
Hi all, I suppose this is a very simple question, but as I've lost already a bit of time with it, without being able to get what I wanted, I'm addressing the question to the group in the hope someone can help me. I pretend to plot the richness of herbaceous species (RichHN) as a function of time since remnant isolation (Isol) conditioned to the area of the remnant (fArea - this is a factor with 3 classes). I also want to differentiate the sites plotted using a grouping binary variable (Urb). So far, I've written this: extinction<-xyplot(RichH...

Split-split plot ANOVA
Does someone out there have an example of R-code for a split-split plot ANOVA using aov or another function? The design is not balanced. I never set up one in R before and it would be nice to see an example before I tackle a very complex design I have to model.
