We have two general strategies to do wrapping; they are as follows:
- Parallelism: We can create two copies of the data and rank each copy. We then need to reassemble the two copies into a final result that includes both rankings. This can be a bit awkward because we'll need to somehow merge two sequences that are likely to be in different orders.
- Serialism: We can compute ranks on one variable and save the results as a wrapper that includes the original raw data. We can then rank this wrapped data on the other variable. While this can create a complex structure, we can optimize it slightly to create a flatter wrapper for the final results.
The following is how we can create an object that wraps a pair with ...
