Labelled vectors for SPSS

Description

This class is only used when user_na = TRUE in read_sav(). It is similar to the labelled() class but it also models SPSS's user-defined missings, which can be up to three distinct values, or for numeric vectors a range.

Usage

labelled_spss(
  x = double(),
  labels = NULL,
  na_values = NULL,
  na_range = NULL,
  label = NULL
)

Arguments

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.

Examples

x1 <- labelled_spss(1:10, c(Good = 1, Bad = 8), na_values = c(9, 10))
is.na(x1)

x2 <- labelled_spss(
  1:10,
  c(Good = 1, Bad = 8),
  na_range = c(9, Inf),
  label = "Quality rating"
)
is.na(x2)
