arrange in R

Sorting rows, ascending by default and descending on request.

library(dplyr)

runs <- tibble(
  lang = c("r", "python", "sql", "go"),
  stars = c(3L, 3L, 1L, NA_integer_),
  tpm = c(96, 104, 79, 88)
)

print(arrange(runs, tpm))
print(arrange(runs, desc(stars), lang))
print(arrange(runs, stars))
print(slice_max(runs, tpm, n = 2))
print(slice_min(runs, tpm, n = 1))

How it works

1. desc() reverses one column's order.
2. Several columns break ties left to right.
3. NA sorts last whichever direction you choose.
