 <p>You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).</p>
 <p>However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated <strong>(a)</strong> provisionally, unless and until the copyright holder explicitly and finally terminates your license, and <strong>(b)</strong> permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.</p>
 <p>Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.</p>

Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance.

 <p>Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.</p>
 <p>An “entity transaction” is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party’s predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.</p>
 <p>You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.</p>

If the Program specifies that a certain numbered version of the GNU General Public License “or any later version” applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation.</p>

+<a href="https://metrumresearchgroup.github.io/mrgda/reference/explain.html" target="_blank">function documentation</a> for additional background and
+examples.</p>
+<p><code><a href="../reference/explain.html">explain()</a></code> prints a formatted message containing the
+result of a provided expression. This function is intended to be run
+interactively in the R console to aid in code understanding, transfer
+and debugging.</p>
+<p>Below, we will go through a few examples cases using
+<code><a href="../reference/explain.html">explain()</a></code>.</p>

+<p>Before performing a data manipulation, we can use
+<code><a href="../reference/explain.html">explain()</a></code> to document why it is needed. This will help
+transfer knowledge of assumptions/decisions made to future authors or
+reviewers.</p>
+<p>For instance, if we’re planning to exclude a record we believe is an
+outlier, we can first use <code><a href="../reference/explain.html">explain()</a></code> to show where in the
+data the issue exists.</p>
