Hi, I would like to know whether it is possible to obtain a value of 
significance for random effects when aplying the lme or related 
functions. The default output in R is just a variance and standard 
deviation measurement.

I feel it would be possible to obtain the significance of these random 
effects by comparing models with and without these effects. However, 
I'm not used to perform this in R and I would thank any easy guide or
