R: lme and lmer Basic Functionality

This is just a quick reference to someone else's work. First of all the basics:
1. lme
http://stat.ethz.ch/R-manual/R-patched/library/nlme/html/lme.html
2. lmer
http://cran.r-project.org/web/packages/lme4/index.html

Professor Vardeman (Iowa State) has posted a very nice summary for the basic functionality of these functions. It is important to heed is warning that these functions are constantly under development (which is generally applicable to R).
