pivot_longer(names_transform = parse_number)

Don't need to use list() to specify the names_transform argument in pivot_longer() if I am applying the same function to all the names columns. Update in tidying data exercises.

library(tidyverse)
library(rcfss)

pivot_longer(
  data = race,
  cols = -Name,
  names_to = "Time",
  values_to = "Score",
  names_transform = parse_number
)
#> # A tibble: 28 × 3
#>    Name   Time Score
#>    <chr> <dbl> <dbl>
#>  1 Carla    50   1.2
#>  2 Carla   100   1.8
#>  3 Carla   150   2.2
#>  4 Carla   200   2.3
#>  5 Carla   250   3  
#>  6 Carla   300   2.5
#>  7 Carla   350   1.8
#>  8 Mace     50   1.5
#>  9 Mace    100   1.1
#> 10 Mace    150   1.9
