elations at short time-lags:</p><ul><li><p><code>0</code> will include the main diagonal in all RQA measure calculations.</p></li>
<li><p><code>1</code> will remove the main diagonal from all RQA measure calculations.</p></li>
<li><p><code>NA</code> (default), will check if the matrix is symmetrical , if so, it will remove the diagonal by setting <code>theiler = 1</code> (Line of Identity, Auto-RQA), if it is not symmetrical (Line of Synchronisation, Cross-RQA) it will set <code>theiler = 0</code>.</p></li>
