The simple way is to check the files in the source code package,
because they include the comments as well as the code.  The source
code archive is stored at http://r-forge.r-projects.org/projects/lme4
under the SCM tab.  A direct URL is

http://r-forge.r-project.org/plugins/scmsvn/viewcvs.php/?root=lme4

The most recent version of the source code for essentially everything
associated with mer objects is in the file pkg/R/lmer.R

In general if you want to examine methods you first decide if you have
an S3 method or an S4 method.  S3 method names are returned by

methods(anova)

and S4 method names by

showMethods("anova")

To display the code for a particular S4 method use

getMethod("anova", "mer")
