Think back to when we defined grouped samples from the Animals Table, like "puppies", "old cats", etc. What grouped samples would be useful for your dataset? List a few of these in the first column.
Then, for each one, define a function that will identify if a row r
is in the subset.
Hint: you can always use a blank design recipe page.
