afex_options {afex} | R Documentation |
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).
afex_options(...)
... |
One of three: (1) nothing, then returns all options; (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). |
The following arguments are currently set:
check.contrasts
should contrasts be checked and changed to sum-to-zero contrasts? Default is TRUE
.
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). (mixed()
only)
return_aov
: Return value of the ANOVA functions (see aov_car
), default is "nice"
.
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 aov_car
or 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)
depends on input, see above.
