[R] identical results with PQL and Laplace options in lmer function (package lme4)

Dear R users I encounter a problem when i perform a generalized linear mixed model (binary data) with the lmer function (package lme4) with R 2.1.0 on windows XP and the latest version of package lme4 (0.96-1) and matrix (0.96-2) both options PQL and Laplace for the method argument in lmer

It's a dumb mistake in the code. I missed a factor of 2 when converting from deviance to log-likelihood in one place. I'll upload a new version of the Matrix package. (It happens that all of the code for lmer is in the Matrix package now so there is no need to update the lme4 package.) On
