with lmer : Erreur dans names(argNew)[1] <- names(formals(new))[[1]]
Without a reproducible example it is difficult to determine why the problem may be manifesting itself. I would note that you are using the car package and there may be an interaction between having car loaded and some of the methods in lme4. However, without a reproducible example and some information on exactly what versions of which packages are attached (i.e. the output from sessionInfo()) this is just speculation.

Hi
While running lmer after lm, I get ?this error message :
Erreur dans names(argNew)[1] <- names(formals(new))[[1]] :
?l'argument de remplacement est de longueur nulle
I don't understand why it appears. I re-start R, and then lmer works.
I suppose the previous work has an influence on lmer; why ?
My previous work:
op<-options(contrasts=c("contr.sum", "contr.treatment"))
resu1<-lm(Y ~ fact1 + bloc_c*bloc_l, data=DF)
Anova(resu1, type="III") ?# library car
summary(resu1)
options(op)
sessionInfo()
