A horrendous hack is employed in order to do arbitrary likelihood ratio tests: the model matrix is built, the names possibly mangled, then fed in as a symbolic formula to glmer/lmer. This is necessary because there is no (easy) way to specify an arbitrary fixed-effect model matrix in glmer.

update
: update the formula or design matrix
vcov
: return the variance/covariance of component which
coef
: return the coefficients. The horrendous hack is attempted to be undone.
logLik
: return the log-likelihood
pseudoMM
part of this horrendous hack.
strictConvergence
logical
(default: TRUE
) return results even when the optimizer or *lmer complains about convergence
optimMsg
character
record warnings from lme. NA_character_
means no warnings.
