[R-pkgs] New versions of Matrix and lme4 packages

[Douglas Bates]

Version 0.98-1 of the lme4 package and of the Matrix package are now
on CRAN.  This version provides the adaptive Gauss-Hermite quadrature
(AGQ) method for fitting generalized linear mixed models.

A new generic function mcmcsamp has been added with a method for
objects in the "lmer" (linear mixed model fit or generalized linear
mixed-effects model fit) class.  This function provides a Markov Chain
Monte Carlo sample from the posterior distribution of the model
parameters.  The returned object has (S3) class "mcmc" and the
diagnostic functions in the coda package can be used on it.
