Meta Information

Meta information that is part of i_labeled objects:

1. label: Variable label
2. labels: Value labels
3. na_values: Missing values
4. na_range: Missing range
5. scale: Scale level
6. wording: Question text in the questionnaire
7. subject: Subject of the variable 8: annotation: Additional information

Meta information can be applied via the class constructor i_labelled (as seen above) or by dedicated functions. Adding meta information by base R's attr() function is also possible.

myVariable <- i_labelled(c(1, 2, 3, -9, NA))

myVariable <- myVariable |>
  i_label("my variable label") |>
  i_labels(
    "A" = 1,
    "B" = 2,
    "C" = 3,
    "X" = -9
  ) |>
  i_na_range(c(-9,-1)) |>
  i_scale("nominal") |>
  i_subject("dummy data")
myVariable
