How should the results be returned: <dl>
<dt>1</dt><dd>Submatrix of data inside <code>reg</code></dd>
 <dt>2</dt><dd>Submatrix of data
outside <code>reg</code></dd>
 <dt>3</dt><dd>Boolean vector, TRUE for data inside
<code>reg</code></dd>
 <dt>4</dt><dd>Boolean vector, TRUE for data outside <code>reg</code></dd><p></p><p><dt>5</dt><dd>Indices of data inside <code>reg</code></dd>
 <dt>6</dt><dd>Indices of data outside
<code>reg</code></dd>
</p></dl>
