[R] as.formula(string) and augPred in lme

Using formulas constructed from strings only
partially works for me in lme:


summary(fm2) # works
augPred(fm2) # fails
#Error in inherits(object, "formula") : 
#Argument "object" is missing, with no default

I assume that my use of as.formula is wrong, but what's the right way?
Or at least a workaround?
