[R-sig-ME] lmer bug

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

Hi Arun:

Did you use the lmer from CRAN or built from Subversion source? This code
indeed works for lmer from CRAN, as I indicated in my original e-mail. I was
just pointing out that it no longer works for lmer from Subversion source.
Which Subversion release number are you using?

Roby
