This report lists the candidate variable for DataScheme variables of the construct physique.

Exposition

This report is meant to be compiled after having executed the script ./manipulation/0-ellis-island.R, which prepares the necessary data transfer object (DTO). We begin with a brief recap of this script and the DTO it produces.

Ellis Island

All data land on Ellis Island.

The script 0-ellis-island.R is the first script in the analytic workflow. It accomplished the following:

    1. Reads in raw data files from the candidate studies
    1. Extract, combines, and exports their metadata (specifically, variable names and labels, if provided) into ./data/shared/derived/meta-data-live.csv, which is updated every time Ellis Island script is executed.
    1. Augments raw metadata with instructions for renaming and classifying variables. The instructions are provided as manually entered values in ./data/shared/meta-data-map.csv. They are used by automatic scripts in later harmonization and analysis.
    1. Combines unit and metadata into a single DTO to serve as a starting point to all subsequent analyses.
