Get One to Many Values that Led to a Prior Error

Usage

get_one_to_many_dataset()

Value

A data.frame or NULL

Details

If assert_one_to_one() detects an issue, the one to many values are stored in a dataset. This dataset can be retrieved by get_one_to_many_dataset().

Note that the function always returns the one to many values from the last error that has been thrown in the current R session. Thus, after restarting the R sessions get_one_to_many_dataset() will return NULL and after a second error has been thrown, the dataset of the first error can no longer be accessed (unless it has been saved in a variable).

Examples

library(admiraldev, warn.conflicts = FALSE)
data(admiral_adsl)

try(
  assert_one_to_one(admiral_adsl, exprs(STUDYID), exprs(SITEID))
)
#> Error in assert_one_to_one(admiral_adsl, exprs(STUDYID), exprs(SITEID)) : 
#>   For some values of STUDYID there is more than one value of SITEID.
#> Call `get_one_to_many_dataset()` to get all one to many values.
