Columns that need to be recoded. See `dplyr::dplyr_tidy_select` for available options.

code_from

vector. the order must match with vector for `code_to`

code_to

vector. the order must match with vector for `code_from`

retain_code

Value

An object of the same type as .data. The output has the following properties: 1. Columns except the recoded columns from .data will be preserved 2. Recoded columns

Examples

pre_recoded_df = tibble::tibble(x1 = 1:5, x2 = 5:1)
recoded_df = recode_item(pre_recoded_df, cols = dplyr::contains('x'),
                        code_from = 1:5,
                        code_to = 5:1)
