zap_na_tags: Convert tagged NA values into regular NA

In sjlabelled: Labelled Data Utility Functions

Convert tagged NA values into regular NA

Description

Replaces all tagged_na() values with regular NA.

Usage

zap_na_tags(x, ...)

Arguments

x	A labelled() vector with tagged_na values, or a data frame with such vectors.
...	Optional, unquoted names of variables that should be selected for further processing. Required, if x is a data frame (and no vector) and only selected variables from x should be processed. You may also use functions like : or tidyselect's select-helpers. See 'Examples'.

Value

x, where all tagged_na values are converted to NA.

Examples

if (require("haven")) {
  x <- labelled(
    c(1:3, tagged_na("a", "c", "z"), 4:1),
    c("Agreement" = 1, "Disagreement" = 4, "First" = tagged_na("c"),
      "Refused" = tagged_na("a"), "Not home" = tagged_na("z"))
  )
  # get current NA values
  x
  get_na(x)
  zap_na_tags(x)
  get_na(zap_na_tags(x))

  # also works with non-labelled vector that have tagged NA values
  x <- c(1:5, tagged_na("a"), tagged_na("z"), NA)
  haven::print_tagged_na(x)
  haven::print_tagged_na(zap_na_tags(x))
}
