set_default_contrasts

set_deviation_contrasts

set_effects_contrasts

set_sum_contrasts

set_treatment_contrasts

These functions are simple wrappers to set contrasts globally via <code>options(contrasts = ...)</code>.

Provides 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).
