I have a little problem about degree of freedom in R.
if you can help me, I will be happy.
I used nlme function to analyze my data and run the linear mixed 
effects model in R.
I did the linear mixed effect analysis in SAS and SPSS as well.
However, R gave the different degrees of freedom than SAS and SPSS did.
Can you help me to learn what the reason is to obtain different 
degrees of freedom from R?
