for some reason TukeyHSD() seems not to want to play with aov-results
with an Error() function:

> Res1<-aov(H2O~location+topo+horizon+pF+Error(location:topo:horizon))
> TukeyHSD(Res1, "topo")
Error in TukeyHSD(Res1, "topo") : no applicable method for "TukeyHSD"

However you could do it by hand by doing all pairwise comparisons and
adapt the confidence interval with Tukey or Scheffe. 
Or do I make a statistical thinking error?
