Description Usage Arguments Details Value Note Examples
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 namevalue pair which sets the corresponding option to the new value (and returns nothing), (4) a list with optionvalue 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 sumtozero contrasts? Default is TRUE
.
type
type of sumsofsquares to be used for testing effects, default is 3 which reports Type 3 tests.
method_mixed
: Method used to obtain pvalues 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 etasquared).
correction_aov
: Correction used for withinsubjects factors with more than two levels for ANOVAs (see aov_car
or nice
), default is "GG"
(GreenhouseGeisser 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 isc(" +", " *", " **", " ***")
.
lmer_function
: Which lmer
function should mixed
or lmer_alt
use. The default is "lmerTest"
which uses lmer
, "lme4"
is also possible which uses lmer
. Note that mixed
methods "KR"
and "S"
only work with "lmerTest"
. For the other methods, "lme4"
could be minimally faster, but does not allow to use lmerTest::anova()
.
depends on input, see above.
All options are saved in the global R options
with prefix afex.
