<p style="line-height: 1.75; margin-bottom: 1.15em;">
r-statistics.co publishes two kinds of material, and they are licensed differently. Please read the section that applies to what you want to use. If you are unsure which category something falls into, or you want to use anything in a way this page does not cover, write to <a href="mailto:[email protected]">[email protected]</a> and ask. We are happy to grant permission for reasonable uses.

The free written tutorials and articles on r-statistics.co (the pages you can read without signing in or paying) are licensed under the <a href="https://creativecommons.org/licenses/by-nc-nd/4.0/" rel="noopener">Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International</a> license.
</p>
<div class="lic-card">
<p style="margin:0 0 8px;font-weight:600;">You may</p>
<ul class="lic-yes">
<li>Share and redistribute a tutorial in its original, unchanged form.</li>
<li>Quote from it and link to it, for teaching, study, or reference.</li>
<li>Use it for non-commercial purposes.</li>
</ul>
<p style="margin:14px 0 8px;font-weight:600;">As long as you</p>
<ul class="lic-yes">
<li>Give clear credit to <strong>r-statistics.co</strong> and link back to the original page.</li>
<li>Do not present it as your own work or imply we endorse you.</li>
</ul>
<p style="margin:14px 0 8px;font-weight:600;">You may not</p>
<ul class="lic-no">
<li>Use it commercially, including reselling it, putting it behind your own paywall, or republishing it on an ad-supported or lead-generation site at scale.</li>
<li>Publish a modified, translated, or derivative version (the "NoDerivatives" term). You may of course learn from it and write your own original material.</li>
<li>Remove attribution or the license notice.</li>
</ul>
</div>
<p style="line-height: 1.75; margin-bottom: 1.15em;">
<strong>Code samples are more permissive.</strong> The short R code snippets shown inside the free tutorials are provided so you can learn and build. You may use them in your own projects, including commercial ones, without attribution. This carve-out applies only to the code itself, not to the surrounding written explanation.
</p>
<h2 class="lic-h2">2. Courses, lessons, exercises, tools, and certificates</h2>
<p style="margin-bottom:.4em;"><span class="lic-badge lic-owned">Copyright © r-statistics.co · All rights reserved</span></p>
<p style="line-height: 1.75; margin-bottom: 1.15em;">

<h2 class="lic-h2">4. Datasets and third-party material</h2>
<p style="line-height: 1.75; margin-bottom: 1.15em;">
Some tutorials use built-in R datasets or other third-party material that carries its own license. Where that is the case, that material stays under its original terms, which take precedence over this page.
</p>
<h2 class="lic-h2">5. Permissions and commercial licensing</h2>
<p style="line-height: 1.75; margin-bottom: 1.15em;">
Want to use something beyond what is allowed here, for example in a paid course, a workshop, a book, or a company training program? We often say yes.
