Swap column values, optionally based on condition

Source: R/transform.R
swap.Rd

swap() swaps values between two columns. swap_if() swaps values only in rows where a condition is met. x and y will be cast to a common type using vctrs::vec_cast_common().

Usage

swap(.data, x, y)

swap_if(.data, cond, x, y, missing = c("NA", "keep", "swap"))

Arguments

x

column to swap with y.

y

column to swap with x.

cond

a logical vector.

missing

what to do if cond is NA.

  • "NA" replaces both x and y with NA.

  • "keep" keeps values in their original columns (as though cond were FALSE).

  • "swap" swaps values between x and y (as though cond were TRUE).
