It is my understanding that the corClass functions are not able to be
used with lmer() at this time.

Subject: [R] covariance structures in lmer


I usually use lme from the nlme library. Now I have read an article
about lmer in Rnews and lmer seemed to me more comfortable to use.
Unfortunately, I didn't find out how to use covariance structures (e. g.
corSymm(), corAR1()). Is there a way to use them similarly as in lme ?
Is it implemented ? If somebody knows, please let me know.

Thank you very much in advance,
