 Dear all,

 I am currently trying to quantify between-individual differences in
intercept and slope of vigilance behavior.
 Here is my model:
model<-lmer(logfreq_vig~logdensity+logbiomasstrue+(1|Idtag),
na.action=na.omit, data=tabimpala)

I would need to obtain the value of Vi (estimator of the intercept
deviation) and Vs (=estimator of the slope deviation) with their Confidence
Interval.
   I have tried the scale function and the lm.beta function to standardize
the variables but it is not working...
  Does someone would have an idea to obtain those values?

Any help would be very appreciated,

 Thanks,
