[R] ANOVA Estimated effects may be unbalanced

[Luis Fernando García Hernández]

Dear All,

This is a data relating leg shaking on differenntre treatments. I reused
several individuals so I want to know 1) if there are significative
differences on shaking per treatment and 2) if the reused individuals
presented some effect or significative variation.

Nevertehless when I make

model1<-aov(Legshaking~Idmale*Idfemale*tratament)

or

model1<-aov(Legshaking~Idmale+Idfemale+tratament)

I get

13744 out of 13824 effects not estimable
Estimated effects may be unbalanced

What could be wrong here? Any advice about how to handle this data in R
will be welcome!

Thanks in advance
