generalized eta-squared (ignored if
Character. Which sphericity correction of the degrees of
freedom should be reported for the within-subject factors. The default is
logical. Should the column containing the Mean Sqaured Error (MSE)
be displayed? Default is
logical. Should intercept (if present) be included in the
ANOVA table? Default is

significance? When entering an vector with
further arguments passed through, see description of return value for details.
same as for
Exploratory ANOVA, for which no detailed hypotheses have been specified a
priori, harbor a multiple comparison problem (Cramer et al., 2015). To avoid
an inflation of familywise Type I error rate, results need to be corrected
for multiple comparisons using
defaults to the method specified in the call to
anova_table. If no method was specified and
NULL p-values are not adjusted.
Returns an ANOVA table of class
"data.frame"). Information such as effect size (
df-correction are calculated each time this method is called.
For ANOVAs containing within-subject factors it
returns the full output of the within-subject tests: the uncorrected
results, results containing Greenhousse-Geisser and Hyunh-Feldt correction,
and the results of the Mauchly test of sphericity (all achieved via
summary.Anova.mlm). For other ANOVAs, the
anova table is
Prints (and invisibly returns) the ANOVA table as

Provide the backbone for
emmeans and related functions from
emmeans directly on
afex_aov objects by returning a
emmGrid-class object. Should not be called directly
but through the functionality provided by emmeans.
