Doubt about nested aov output

Hi,

I have two doubts about the nested aov output.

1) I have this:

anova.ratos <- aov(Glicogenio~Tratamento+Error(Tratamento/Rato/Figado))
summary(anova.ratos)

Error: Tratamento
           Df  Sum Sq Mean Sq
Tratamento  2 1557.56  778.78

Error: Tratamento:Rato
          Df Sum Sq Mean Sq F value Pr(>F)
Residuals  3 797.67  265.89               

Error: Tratamento:Rato:Figado
          Df Sum Sq Mean Sq F value Pr(>F)
Residuals 12  594.0    49.5               

Error: Within
          Df Sum Sq Mean Sq F value Pr(>F)
Residuals 18 381.00   21.17               

R dont make the F and P automatically, it is possible?

I Like an output like this:

Error: Tratamento
           Df  Sum Sq Mean Sq F value Pr(>F)
Tratamento  2 1557.56  778.78   2.929 0.197

Error: Tratamento:Rato
          Df Sum Sq Mean Sq F value Pr(>F)
Residuals  3 797.67  265.89   5.372 0.0141      

Error: Tratamento:Rato:Figado
          Df Sum Sq Mean Sq F value Pr(>F)
Residuals 12  594.0    49.5   2.339 0.0503        

Error: Within
          Df Sum Sq Mean Sq F value Pr(>F)
Residuals 18 381.00   21.17         

Why it not make automatic calculations? It is possible?


2) I can say that Error: Tratamento:Rato means an interaction between 
Tratamento and Rato? Normally the : represents an interaction, but in this 
output I think that it dont mean the interaction. 

Any explanation are welcome.

Thanks
Ronaldo
