[R] Anova's in R

[Frith Jarrad]

Hello.

I am looking for some help using anova's in RGui.

My experiment ie data, has a fixed burning treatment (Factor A) 2 levels, 
unburnt/burnt.
Nested within each level of Factor A are 2 random sites (Factor B).
All sites are crossed with a fixed temperature treatment (Factor C) 2 
levels, 0 degreesC/2 degreesC, with many replicates of these temperature 
treatments randomly located at each site.

I am trying the following
aov(dependent 
variable~burning*temperature*site+Error(replicate),data=dataset) and 
variations on that, however can't get it quite right.... the F ratios are 
not correct. I imagine this is a fairly common experimental design in 
ecology and would ask that anyone who has some advice please reply to this 
email?

Thank-you,
Frith
