[R-sig-ME] mer-class in lme4 package

[Cantieni Andrea PHZ Schwyz]

Hi,

I'm trying to access the transpose of model matrix  (Zt) for the random effects of an object returned by lmer().

In lme4.0 v0.999999-1 that is easy done via the slots, e.g. fm01 at Zt, where fm01 is an object of class "mer".

Can someone explain why this slot (and others) disappeared, e.g. in lme4 v0.99999911-0? And how I can access this properties anyway?

Thanks,
Andrea
