detect_boundary_num | R Documentation |
Detect for each numerical variable in a validation rule set, what its maximum and minimum values are.
This allows for manual rule set checking: does rule set x
overly constrain numerical values?

This procedure only finds minimum and maximum values, but misses gaps.
