labelled_spss_survey: Labelled vectors for multiple SPSS surveys
In retroharmonize: Ex Post Survey Data Harmonization

Description Usage Arguments Details See Also Examples

This class is amending haven::labelled_spss with a unique object identifier id to make later binding or joining reproducible and well-documented.

labelled_spss_survey(
  x = double(),
  labels = NULL,
  na_values = NULL,
  na_range = NULL,
  label = NULL,
  id = NULL,
  name_orig = NULL
)

as_character(x)

is.labelled_spss_survey(x)

as_numeric(x)

`x`	A vector to label. Must be either numeric (integer or double) or character.
`labels`	A named vector or `NULL`. The vector should be the same type as `x`. Unlike factors, labels don't need to be exhaustive: only a fraction of the values might be labelled.
`na_values`	A vector of values that should also be considered as missing.
`na_range`	A numeric vector of length two giving the (inclusive) extents of the range. Use `-Inf` and `Inf` if you want the range to be open ended.
`label`	A short, human-readable description of the vector.
`id`	Survey ID
`name_orig`	The original name of the variable. If left `NULL` it uses the latest name of the object `x`.

It inherits many methods from labelled, but uses more strict coercion and validation rules.
