Dimitris,

thanks, but it dont work.

model <- lme(height~seed,random=~time|rep/seed,control=list(niterEM = 10))
Erro em lme.formula(height ~ seed, random = ~time | rep/seed, control = 
list(niterEM = 10)) : 
	iteration limit reached without convergence (9)
> model <- lme(height~seed,random=~time|rep/seed,control=list(niterEM = 100))
Erro em lme.formula(height ~ seed, random = ~time | rep/seed, control = 
list(niterEM = 100)) : 
	iteration limit reached without convergence (9)
> model <- lme(height~seed,random=~time|rep/seed,control=list(niter = 100))
Erro em lme.formula(height ~ seed, random = ~time | rep/seed, control = 
list(niter = 100)) : 
	iteration limit reached without convergence (9)
