Hi Nastia,
» I still struggle to understand what is the difference between lmer and lme in this case...
The syntax of the formula for random effects is different.
The method to extract the PE and calculate the CI is also different. Hint: Lines 53–56 and 80–84 of the source-code of

The syntax of the formula for random effects is different.
mod <- lmer(logPK ~ sequence + period + treatment +
(1|subject),
data = data)
mod <- lme(log(PK) ~ sequence + period + treatment,
random = ~1|subject,
data = data, na.action = na.omit)
lme() you have to use na.action = na.omit because the default na.action = na.fail would stop and throw an error.The method to extract the PE and calculate the CI is also different. Hint: Lines 53–56 and 80–84 of the source-code of
