harmonize_values {retroharmonize}

Harmonize the values and labels of labelled vectors

Description

Harmonize the values and labels of labelled vectors

Usage

harmonize_values(
  x,
  harmonize_label = NULL,
  harmonize_labels = NULL,
  na_values = c(do_not_know = 99997, declined = 99998, inap = 99999),
  na_range = NULL,
  id = "survey_id",
  name_orig = NULL,
  remove = NULL,
  perl = FALSE
)

Arguments

x

A labelled vector

harmonize_label

A character vector of 1L containing the new, harmonize variable label. Defaults to NULL, in which case it uses the variable label of x, unless it is also NULL.

harmonize_labels

A list of harmonization values

na_values

A named vector of na_values, the observations that are defined to be treated as missing in the SPSS-style coding.

na_range

A min, max range of na_range, the continuous missing value range. In most surveys this should be left NULL.

id

A survey ID, defaults to survey_id

name_orig

The original name of the variable. If left NULL it uses the latest name of the object x.

remove

Defaults to NULL. A character or regex that will be removed from all old value labels, like "\("|\) for ( and ).

perl

Use perl-like regex? Defaults to FALSE.

Value

A labelled vector that contains in its metadata attributes the original labelling, the original numeric coding and the current labelling, with the numerical values representing the harmonized coding.

Examples

var1 <- labelled::labelled_spss(
  x = c(1,0,1,1,0,8,9), 
  labels = c("TRUST" = 1, 
             "NOT TRUST" = 0, 
             "DON'T KNOW" = 8, 
             "INAP. HERE" = 9), 
  na_values = c(8,9))

harmonize_values (
  var1, 
  harmonize_labels = list ( 
    from = c("^tend\\sto|^trust", "^tend\\snot|not\\strust", "^dk|^don", "^inap"), 
    to = c("trust", "not_trust", "do_not_know", "inap"),
    numeric_values = c(1,0,99997, 99999)), 
    na_values = c("do_not_know" = 99997,
                "inap" = 99999), 
    id = "survey_id"
