Set Variable Attributes from AmericasBarometer Notes
lpr_set_attr.Rd
Applies notes stored in a data frame object as attributes to corresponding variables in AmericasBarometer dataset. This is particularly useful for setting variable labels, question wording, or other metadata from extracted notes.
Arguments
- data
A data frame whose variables will receive new attributes
- notes
A data frame containing notes information, typically produced by
lpr_extract_notes
. Must contain columns: variable_name, note_id, and note_value.- noteid
Character string specifying which note ID to extract from the notes data frame (e.g., "label" for variable labels, "qtext" for question text).
- attribute_name
Character string specifying the attribute name to set (e.g., "label", "qwording", "roslabel").
Details
This function:
Filters the notes data frame to only include rows matching the specified `noteid`
Loops through each matching note and applies it as an attribute to the corresponding variable in the data frame
Issues warnings for variables in the notes that don't exist in the data
The function is designed to work in tandem with lpr_extract_notes
, creating
a workflow for managing variable metadata in AmericasBarometer data.
