[R-sig-ME] var-covar matrix in ranef

[Hester Lingsma]

Dear R users,
If I fit a model with a random slope and a random intercept, the 
var-covar matrix derived from PostVar from the function ranef is a 2 by 
2 matrix for each upper level subject. I want to use the posterior 
estimates (from ranef) and their standard error from both the slope and 
the intercepct for each upper level subject. Which elemants of the 2 by 
2 matrixes to use for the se of the posterior estimate?
Thanks,
Hester
