Fitting Linear Mixed-Effects Models using lme4
cran.r-project.orgAt present, the main alternative to lme4 for mixed modeling in R is the nlme package (Pin-heiro, Bates, DebRoy, Sarkar, and R Core Team 2014). The main features distinguishing lme4 from nlme are (1) more efficient linear algebra tools, giving improved performance on

Multilevel Modeling in R (2.6)
cran.r-project.orgbrief description of the lme4 package. The lme4 package was developed by Doug Bates and extends one’s ability to estimate mixed-effects models in several important ways (two are which are when one’s dependent variable is dichotomous and the other is when data are partially-crossed or fully crossed instead of being fully nested).
Distinguishing Between Random and Fixed
www.web.pdx.eduAnalyses using both fixed and random effects are called “mixed models” or "mixed effects models" which is one of the terms given to multilevel models. ... In SPSS Mixed and R (nlme or lme4), the user must specify which intercepts or slopes should be estimated.

On the other hand, the more recent package lme4 offers an efficient computational implementation and an enhanced syntax, though at the cost of a more restricted choice of LMMs. All classes of linear models presented in the book are illustrated using data from a particular dataset. In this way, the differences between the various
