This means that for a dense, <i>m x n</i> matrix <code>Q</code> and a list <code>L</code>, if <code>Q[i,j]</code> is <code>TRUE</code> then <i>j</i> is an element of <code>L[[i]]</code>. Reversed: when <i>k</i> is the value of <code>L[[i]][j]</code>, then <code>Q[i,k]</code> is <code>TRUE</code>. </p> <hr /><div style="text-align: center;">[Package <em>sf</em> version 0.9-5 <a href="00Index.html">Index</a>]</div> </body></html>
