Recodes a set of columns so that values in ones become 1, values in zeros become 0, and values in na_values become NA.

Usage

recode_binary(data, vars, ones = c(1, 2), zeros = 0, na_values = 98)

Arguments

data

A data frame.

vars

A character vector of column names to recode.

ones

Numeric vector of values to recode to 1. Defaults to c(1, 2).

zeros

Numeric vector of values to recode to 0. Defaults to 0.

na_values

Numeric vector of values to recode to NA. Defaults to 98.

Value

data with recoded columns.

Examples

d <- data.frame(x = c(0, 1, 2, 98))
recode_binary(d, "x")
#>    x
#> 1  0
#> 2  1
#> 3  1
#> 4 NA
