Examples

# Example 1 ----------------------------------
# add the `mcnemar.test(correct)` argument to an ARD structure
ard_formals(fun = mcnemar.test, arg_names = "correct")
#> # An ARD data frame: 1 × 3
#>   stat_name stat_label stat  
#> * <chr>     <chr>      <list>
#> 1 correct   correct    TRUE  

# Example 2 ----------------------------------
# S3 Methods need special handling to access the underlying method
ard_formals(
  fun = asNamespace("stats")[["t.test.default"]],
  arg_names = c("mu", "paired", "var.equal", "conf.level"),
  passed_args = list(conf.level = 0.90)
)
#> # An ARD data frame: 4 × 3
#>   stat_name  stat_label   stat
#> * <chr>      <chr>      <list>
#> 1 mu         mu            0  
#> 2 paired     paired        0  
#> 3 var.equal  var.equal     0
