I had originally thought maybe this vignette would be called "Group-wise metrics" but it ended up being a bit more general than that.

with a title like that, we might wanna preface a little earlier that this isn't about grouped data sets

with a title like the one currently suggested or the previous "Group-wise metrics"? and in some ways, this is indeed about grouped data.

i get worried, and confused myself a little bit, when we have this new methods, that share close names with group_by() related stuff.
I was thinking of having a "when we say X we talk about ABC, and when we say Y we talk about XYZ"

Trying to talk about functions as objects while adhering to tidyverse style is a bit difficult here. I'm game for however yall want to approach this. :)

On board for all of your changes, thank you @juliasilge! Ah, no, that's super important to get right! I'm all for transitioning from "group-wise" to "groupwise". Any thoughts on whether we should then write "group aware" instead of "group-aware"? |

Awesome, we'll keep that, then. After putting 9145ba1 together, I do also appreciate that the way we write "groupwise" in text aligns with how it appears in code. :) Thanks again.🐙 |
