[R-sig-ME] extracting values from lmer

[espesser]

  Hi Kevin,
Maybe there is a better way (a function) , but you can use:

yourmodel at deviance["sigmaREML"]

it returns the residual std. dev.   :  0.13636
(in case of the default setting for lmer()  , i.e. REML=TRUE)
More generally,  " str(yourmodel)   "   gives useful informations  .
R
