Object with class tbl_summary from the tbl_summary function

List of formulas specifying statistical tests to perform for each variable, e.g. list(all_continuous() ~ "t.test", all_categorical() ~ "fisher.test"). Common tests include "t.test", "aov", "wilcox.test", "kruskal.test", "chisq.test", "fisher.test", and "lme4" (for clustered data). See tests for details, more tests, and instruction for implementing a custom test.

Tests default to "kruskal.test" for continuous variables ("wilcox.test" when "by" variable has two levels), "chisq.test.no.correct" for categorical variables with all expected cell counts >=5, and "fisher.test" for categorical variables with any expected cell count <5.

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)).

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.

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().

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)
