Dear r-helpers, When I issue the commands plot(augPred(mcc.lme, primary = ~ mcc$age, length.out = 2, level = c (0, 1))) or plot(comparePred(mcc1.lis, mcc.lme, primary = ~ mcc$age, length.out = 2), layout = c(4, 3))) no lines are drawn. But fm1 <- lme(Orthodont) plot(augPred(fm1, level = 0:1, length.out = 2)) does plot lines. augPred() and comparePredict() seem to be working correctly, as shown below augPred(mcc.lme, primary =...

Dear R-users I am relatively new to R, i hope my many novice questions are welcome. I have problems accessing some objects (specifically the random effects, correlation structure and variance function) from an object of class gls and lme. I used the following models: yah <- gls (outcome~ -1 + as.factor(Trial):as.factor(endpoint)+
