Get Many to One Values that Led to a Prior Error
Details
If assert_one_to_one() detects an issue, the many to one values are stored
in a dataset. This dataset can be retrieved by get_many_to_one_dataset().
Note that the function always returns the many to one values from the last
error that has been thrown in the current R session. Thus, after restarting
the R sessions get_many_to_one_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).
