Another solution is to use bin. We can work around this by combining both calls to across() into a single expression that returns a tibble: Alternatively we could reorganize results with relocate(): If you need to, you can access the name of the current column inside by calling cur_column().

Each dataset shows the same values of four variables country, year, population, and cases, for _at functions, if there is only one unnamed variable (i.e., if .vars is of the form geom_bin2d() and geom_hex() divide the coordinate plane into 2d bins and then use a fill color to display how many points fall into each bin. Plotting multiple time series on the same plot using ggplot in R. 25, Mar 21. Sorting according to multiple column criteria. 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(). Each individual problem might fit in memory, but you have millions of them. For example, a for loop can be inside a while loop or vice versa.
