If by='rule' the relative numbers are computed with respect to the number of records for which the rule was evaluated. If by='record' the relative numbers are computed with respect to the number of rules the record was tested agains. By default the most failed validations and records with the most fails are on the top.When by='record' and not all validation results have the same dimension structure, a list of data.frames is returned.
