Description: 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 (i.e., split-plot) ANOVAs for data
        in long format (i.e., one observation per row), automatically
        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 or Satterthwaite approximation for degrees of
        freedom (LMM only), parametric bootstrap (LMMs and GLMMs), or
        likelihood ratio tests (LMMs and GLMMs). afex_plot() provides a
        high-level interface for interaction or one-way plots using
        ggplot2, combining raw data and model estimates. afex uses type
        3 sums of squares as default (imitating commercial statistical
        software).
