Reordering columns in R

relocate moves columns without listing every other one.

library(dplyr)

runs <- tibble(
  tpm = c(96, 104),
  accuracy = c(97.2, 99.1),
  lang = c("r", "python"),
  day = c(1, 2)
)

print(relocate(runs, lang))
print(relocate(runs, lang, day, .before = tpm))
print(relocate(runs, where(is.numeric), .after = last_col()))
print(names(select(runs, lang, everything())))

How it works

1. .before and .after take a column name or a selection.
2. A selection helper moves a whole group at once.
3. select with everything() does the same by listing.
