When I try to adjust a mixed model with random effects I can make this order without problem
> lm.FA<-lme(absFA~trait*condition,random=~1|individual) But if I try to fit a model in which the response (absFA) is not the same in all individuals at different levels of "trait" factor , but varies randomly from each. That is, this order > lm.FA2<-lme(absFA~rasgo*condicion,random=~rasgo|individuo) R hangs and crashes, I've tried both with R 2.13 and with R 2.15. ----- Mario Garrido Escudero PhD student Dpto. de Biología Animal, Ecología, Parasitología, Edafología y Qca.
