<li>Calculate the UNF for each variable, as above.</li>

<p>Note (a): For one-variable datasets, Dataverse implements the algorithm at the variable-level only, without aggregation. Thus a UNF for a one-variable dataframe is the same as the UNF for that variable alone. The standard is ambiguous in this regard and the package copies the Dataverse implementation.</p>
<p>Note (b): The package treats dataframes and lists identically. Matrices are coerced to data
