Using the mutate function in R

What is the easiest/best way to use the mutate() function in R?

See below for the best way :grinning:
If you tune your question, I can try to tune my answer


df1 <- data.frame(
  x = 1:3

df2 <- df1 |>
    y = 2*x,
    z = case_when(
      y <  3 ~ "small",
      y == 4 ~ "fair",
      TRUE   ~ "must be large"

#>   x y             z
#> 1 1 2         small
#> 2 2 4          fair
#> 3 3 6 must be large

Thanks for that. How about using mutate() to create new columns form an existing data frame? Also, how can summarize() be used to make summaries if total sums/averages? Thanks so much.
