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
