A window function is a variation on an aggregation function. This can be useful if you want to perform some sort of context dependent transformation thats already encoded in a vector: Be careful when combining numeric summaries with where(is.numeric): Here n becomes NA because n is numeric, so the across() computes its standard deviation, and the standard deviation of 3 (a constant) is NA.

This is different to the behaviour of mutate_if(), mutate_at(), and mutate_all(), which apply the transformations one at a time. You probably want to compute n() last to avoid this problem: Alternatively, you could explicitly exclude n from the columns to operate on: Another approach is to combine both the call to n() and across() in a single expression that returns a tibble: So far weve focused on the use of across() with summarise(), but it works with any other dplyr verb that uses data masking: Rescale all numeric variables to range 0-1: For some verbs, like group_by(), count() and distinct(), you can omit the summary functions: Count all combinations of variables with a given pattern: across() doesnt work with select() or rename() because they already use tidy select syntax; if you want to transform column names with a function, you can use rename_with().
