Should we differentiate splitting and aggregation for iteration

Hi Will,

In the manual it says

The iteration argument of tar_target() controls the splitting and aggregation protocol on a target-by-target basis

Could we say something like "iterations determines how the current target is aggregated, and split the current target for downstream analysis"? When we lump both splitting and aggregating together, I would not be 100% sure what is the iteration parameter is doing to the target that I am writing.

This understanding comes from using iteration = "group" before iteration = "list", where the first iteration splits for the second target, and the second iteration determines how the results will be returned, and how it will be split next.

Sure, I just edited that section in a0bc54b. Hopefully it is clearer now.

Oh yes definitely. It helped improve my understanding of stems and patterns as well. Thanks!
