Hi,

I make this model using lme

m.lme <- lme(Glycogen~Treatment,random=~1|rTrt/Liver)

How to make this using lmer?

I try

> m.lmer <- lmer(Glycogen~Treatment+(1|rTrt/Liver))
Erro em lmer(Glycogen ~ Treatment + (1 | rTrt/Liver)) :

        entry 0 in matrix[0,0] has row 2147483647 and column 2147483647 AlÚm disso: Mensagem de aviso:
/ not meaningful for factors in: Ops.factor(rTrt, Liver)

lmer dont accept / for make nesting or splitplot analysis?

Thanks

Ronaldo

ps. where I can find more lmer documentation?
