Dear Goran, It's not clear from your question what you want to do, but my guess is that you simply what a "printout" of your results. The usual way to obtain that is via the summary() function. In your case summary(Output). That's typical of statistical modeling functions in R: They return objects, which can be used for further computing, rather than directly producing printouts. If my guess is correct, then you probably should learn more about statistical modeling in R, and about R in general, before using it in your work. One more thing: I doubt whether the command Output <- lmer(G10ln ~ v191_ms + (1 | couno), data = 'G10R') actually works. The data argument should be a data frame, not the *name* of a data frame, i.e., data = G10R .

I am going crazy for a very simple reason. I can?t access the output from for instance the lme4 package in R. I have been able to import an SPSS file into an R data frame. I have downloaded and installed the Lme4 package and I think I have also learnt how to produce a mixed model with lmer: > > Output <- lmer(G10ln ~ v191_ms + (1 | couno), data = 'G10R') > > How shall I define the output from lmer?
