Codebook

This codebook is reconstructed by the IRW from the IRW data standard and the script that built it, lessR.R. It is our best reading, not the source’s own codebook, and it may contain mistakes. Where the two disagree, the source data are the authority. If you find an error, please tell us.

Column	What it is	Source column

`id`	IRW standard Identifier for the focal unit being measured — typically a person, but sometimes another entity (e.g., a word in a lexical task).	made in the build script

What item codes and covariate values stand for is in the package’s documentation, lessR::dataMach4.
