[R-sig-ME] lmList error in lme4a

[David A Springate]

Dear all,

I am trying to use the lmList function from lme4a, but I get the
following error even with the example sleepstudy dataset:

> require(lme4a)
> lmList(Reaction ~ Days | Subject, sleepstudy)
Call: lmList(formula = Reaction ~ Days | Subject, data = sleepstudy) 
Coefficients:
Error in sprintf(gettext(fmt, domain = domain), ...) : 
  invalid type of argument[1]: 'language'

Am I missing something or is this a bug?

Thanks,

David
