Global afex options are used, for example, by
aov_car (et al.) and
mixed. But can be changed in each functions directly using an argument (which has precedence over the global options).
One of four: (1) nothing, then returns all options as a list; (2) a name of an option element, then returns its' value; (3) a name-value pair which sets the corresponding option to the new value (and returns nothing), (4) a list with option-value pairs which sets all the corresponding arguments. The example show all possible cases.
The following arguments are currently set:
check_contrasts should contrasts be checked and changed to sum-to-zero contrasts? Default is
type type of sums-of-squares to be used for testing effects, default is 3 which reports Type 3 tests.
method_mixed: Method used to obtain p-values in
mixed, default is
"KR" (which will change to
"LRT" soon). (
return_aov: Return value of the ANOVA functions (see
aov_car), default is
es_aov: Effect size reported for ANOVAs (see
aov_car), default is
"ges" (generalized eta-squared).
correction_aov: Correction used for within-subjects factors with more than two levels for ANOVAs (see
nice), default is
"GG" (Greenhouse-Geisser correction). (ANOVA functions only)
factorize: Should between subject factors be factorized (with note) before running the analysis? Default is
TRUE. (ANOVA functions only)
sig_symbols: Default significant symbols used for ANOVA and
mixed printing. Default is
c(" +", " *", " **", " ***").
lmer function should
lmer_alt use. The default is
"lmerTest" which uses
"lme4" is also possible which uses
lmer. There should be no difference between the two. The latter could be minimally faster, but does not allow to use
depends on input, see above.
All options are saved in the global R
options with prefix
