[R-sig-ME] Coefficient of determination (R^2) when using lme()

[MHH Stevens]

Hi R.S.,
This quantity is not clearly defined for mixed models --- should it  
include that which is "explained" by the random effects? What would  
it mean to "explain" a response with a variance? In any event, try  
searching R-help lists for Coefficient of determination AND lme.
Cheers,
Hank
