Hi,

I try to run the example of Crawley's Book on the page 661, but it fail,
look

> repmeasures <-
read.table("../Packages/Crawley/data/repmeasures.txt",header=T)
> attach(repmeasures)
> rep <- as.factor(rep)
> library(nlme)
> model <- lme(height~seed,random=~time|rep/seed)
Erro em lme.formula(height ~ seed, random = ~time | rep/seed) :
	iteration limit reached without convergence (9)

I try to increase the iteration but dont fix the problem.

I run this using R 2.2.1 on Debian/Linux and on Windows XP, the problem is the
same.

Why this data dont run.

Thanks
Ronaldo
