ll_to_character: Get the character representation of a labelled variable

In zmisc: Vector Look-Ups and Safer Sampling

Get the character representation of a labelled variable

Description

Returns a character representation of a labelled variable, using the value labels to look up the label for a given value.

The default behavior of this function is similar to labelled::to_character(). The options, however, are slightly different. Most importantly, instead of specifying NA handling using parameters, the function relies on the default parameter to determine what happens for unlabelled variables, allowing users to specify including the original values of x instead of the labels, returning NA, or returning a specific string value. Also, the default behavior is to drop any variable label attribute, in line with the default as.character() method.

Usage

ll_to_character(x, default = x, preserve_var_label = FALSE)

Arguments

x	A labelled variable
default	Vector providing a default label for any values not found in the val_labels (unlabelled values). Must be of length 1 or of the same length as x. Useful possibilities are x (use values where labels are not found), NA (return NA for such values), and "" (an empty string). Missing (NA) values in x, however, are never replaced with the default, they remain NA.
preserve_var_label	Should any var_label in x be preserved, or should they be dropped from the result (ensuring that the result is bare and without any attributes).
