[R-sig-ME] Predictions from lme and lmer models

[Patrick Connolly]

The call to predict with lme models has an argument 'level' which, I
understand, produces population predictions for level = 0 and group
specific predictions for level = 1.

There doesn't seem to be a similar argument for lmer (lme4 package)
models.  Is it just a matter of specifying the appropriate newdata
data frame to achieve the same end?  Or is there a more direct way?

TIA
