R help - Nov 2009 - residuals(lme) error message

Dear R-help,

I am trying to perform residual diagnostics on a repeated measures mixed
effect model. With 3 time points as the fixed effect and subjects as the
random effects.

> time.linearc<- summary(lmer(cnim~(as.factor(time)), random= ~1|subj,
data=ex.rmc, na.action=na.omit))
> time.linearc
 When I perform :
>res <- residuals(time.linearc)
I receive the following error message:

Error in val[, level] : incorrect number of dimensions

If possible could someone explain the problem?


Thanks,

Rupa
