[R] repeated measures anova, car package

[Kay Cichini]

Hello John,

As you said, I could also take a means model and test linear hypothesis for
the desired effects - would this also be the case for the repeated measure i
did in the first place. 
I copied the model from the car model where you first call: 

> modx<-lm(cbind(div_h, div_l) ~ site, divrep)

(?Could I test linear hypothesis here, instead of continuing as I did
beneath)

> idat
  cover
1  high
2   low

> (av.ok1 <- Anova(modx, idata=idat, idesign=~cover))
