subsetting strategy

[janrito]

The documentation on subsets is a bit sparse. Is there a way of creating more complex strategies for subsetting?

i.e. interactions often occur between tables: products, orders, customers, a percentage of products might leave a lot of empty orders, or a lot of products not bought.

What if I wanted:

• a subset of users based on a random sample
• a subset of those users orders, maybe based on a specific time period (the last three months)
• a subset of products—maybe all the ones in the orders above, plus a few random extra ones
