The aim of the ez package for R is to provide a simplified/unified interface to common analysis techniques, including analysis of variance and mixed effects modeling.
This site not only hosts the ongoing code development for ez, but also serves as the forum (https://github.com/mike-lawrence/ez/issues) to report bugs and request features associated ez.
A discussion forum can be found at http://groups.google.com/group/ez4r
To automatically download and install the very latest ez code any time you run a given R script, install the devtools library (install.packages('devtools'); windows users will also have to install Rtools, http://cran.r-project.org/bin/windows/Rtools/, and install devtools via install.packages('devtools',type='source')) then put the following at the top of your script:
library(devtools)
dev_mode()
install_github('ez','mike-lawrence')
library(ez)
