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
