<p>Here we are creating a new object from an existing one:</p>
<pre class="r"><code>new_rivers &lt;- sample(rivers, 5)
new_rivers</code></pre>
<pre><code>## [1] 735 1459 1038 411 329</code></pre>
<pre><code>## [1] 600 465 407 202 360</code></pre>
<p>Using just this will only print the result and not actually change <code>new_rivers</code>:</p>
<pre class="r"><code>new_rivers + 1</code></pre>
<pre><code>## [1] 736 1460 1039 412 330</code></pre>
<pre><code>## [1] 601 466 408 203 361</code></pre>
<p>If we want to modify <code>new_rivers</code> and save that modified version, then we need to reassign <code>new_rivers</code> like so:</p>
<pre class="r"><code>new_rivers &lt;- new_rivers + 1
new_rivers</code></pre>
<pre><code>## [1] 736 1460 1039 412 330</code></pre>
<pre><code>## [1] 601 466 408 203 361</code></pre>
<p>If we forget to reassign this can cause subsequent steps to not work as expected because we will not be working with the data that has been modified.</p>
