r-cran-afex - 1.2-1-1 main

The r-cran-afex package is a GNU R package providing convenience
functions for analyzing factorial experiments using ANOVA or mixed
models. aov_ez(), aov_car(), and aov_4() allow specification of between,
within (i.e., repeated- measures), or mixed between-within (i.e., split-
plot) ANOVAs for data in long format (i.e., one observation per row),
potentially aggregating multiple observations per individual and cell of
the design. mixed() fits mixed models using lme4::lmer() and computes
p-values for all fixed effects using either Kenward-Roger approximation
for degrees of freedom (LMM only), parametric bootstrap (LMMs and
GLMMs), or likelihood ratio tests (LMMs and GLMMs). afex uses type 3
sums of squares as default (imitating commercial statistical software).
