 `imap()` handy for iterating over something and its names or integer indices at the same time.
 
-When you have multiple values for a single unit in one row (e.g. repeated measures), consider reshaping for easier computation. That turns a row-oriented problem into `group_by()` + `summarise()`, which is usually easier.
-
 `dplyr::case_when()` helps you get rid of hairy, nested `if () {...} else {...}` statements.
