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,
