[R-sig-ME] Questions about porting pedigreemm to the new lme4

[Joehanes, Roby (NIH/NHLBI) [F]]

Hi:

I am trying to port pedigreemm to use the new lme4. However, the new lme4 is somewhat opaque to me and hence I need help. Specifically, how can I extract the following terms:
lmf$FL$trms[[tn]]$Zt
lmf$FL$trms[[tn]]$A

The information lies within lmf at pp object, but it is too opaque to me to fish anything out.

I understand that lmf$FL$fl is lmf at flist and that lmer_finalize calls should be replaced with optwrap and mkMerMod. Nevertheless, I think that the lmer or glmer could use some refactoring to ease the calls.

I appreciate any help on these.

Thanks,
Roby
