Arguments
x
Object with class tbl_summary from the tbl_summary function
test
List of formulas specifying statistical tests to perform for each
variable.
Default is two-way ANOVA when by= is not NULL, and has the same defaults
as add_p.tbl_continuous() when by = NULL.
See tests for details, more tests, and instruction for implementing a custom test.
pvalue_fun
Function to round and format p-values.
Default is style_pvalue.
The function must have a numeric vector input (the numeric, exact p-value),
and return a string that is the rounded/formatted p-value (e.g.
pvalue_fun = function(x) style_pvalue(x, digits = 2) or equivalently,
purrr::partial(style_pvalue, digits = 2)).
include
Variables to include in output. Input may be a vector of
quoted variable names, unquoted variable names, or tidyselect select helper
functions. Default is everything().
test.args
List of formulas containing additional arguments to pass to
tests that accept arguments. For example, add an argument for all t-tests,
use test.args = all_tests("t.test") ~ list(var.equal = TRUE)
group
Column name (unquoted or quoted) of an ID or grouping variable.
The column can be used to calculate p-values with correlated data.
Default is NULL. See tests for methods that utilize the group= argument.
