Reads responses files

This function reads response files downloaded from the IQB Testcenter and prepares them for further processing with code_responses(). Rows with empty response payloads are kept as rows with responses = NA so that the observed unit structure remains available; final missing codes are assigned later by complete_design() when the coded data are checked against the full test design. The raw nested response slot ids are checked for missing required slots and unexpected new slots, but the returned data are not changed by these diagnostics.

Usage

read_responses(files, diagnostics = c("compact", "full", "none"))

Arguments

files

diagnostics

Character. Controls response slot diagnostics. Use "compact" for concise feedback, "full" for all details, or "none" to suppress these diagnostics.

A tibble.
