R code to generate unique ID with prefix?
<p>I have a table called "pipel" that contains more than 10,000 rows. I would like to add an ID column to assign a unique ID for each row. The unique ID must be 30 digits long and starts with "AKM_CC_Test_". I used the code below as a starting point but not sure how to format it to add the prefix and make it 30 digits long.</p>

<pre><code>id &lt;- rownames(pipel)
pipel &lt;- cbind(id=id, pipel)
</code></pre>

<p>For example first row ID will need to look like this AKM_CC_Test_000000000000000001</p>
