lumns use different notations for names
(<code><a href="https://matthewheun.github.io/RCLabels/reference/bracket_notation.html" class="external-link">RCLabels::bracket_notation</a></code> for rows and
<code><a href="https://matthewheun.github.io/RCLabels/reference/arrow_notation.html" class="external-link">RCLabels::arrow_notation</a></code> for columns). The renaming and
aggregation capabilities of <code>matsbyname</code> still work, despite
the different notations.</p>
