Get Duplicate Records that Led to a Prior Error
Details
Many {admiral} function check that the input dataset contains only one record
per by_vars group and throw an error otherwise. The get_duplicates_dataset()
function allows one to retrieve the duplicate records that lead to an error.
Note that the function always returns the dataset of duplicates from the last
error that has been thrown in the current R session. Thus, after restarting the
R sessions get_duplicates_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).
