Dear Ebrahim, We do not deal with study or work assignments in this group. I'd suggest, nonetheless, to look into the lme4 package and the mer-class objects created with this package. Regards,

I have been asked to compute standard error of the mean of samples using "residual maximum likelihood (REML)" however, I couldn't find any function in R to do it. All I could find were the function "lmerTest" that do maximum likelihood for the fixed effects modelling but not for computing the "standard error of the mean". I would appreciate any clue.
