title: Could not find function "mutate"
body: <p>I'm running into a problem running the following code:</p>
  <pre><code>brazil &lt;- brazil %&gt;% mutate (
    ID = paste0(country, block, respondentID)
  )
  </code></pre>
  <p>where I get the error:</p>
  <blockquote>
  <p>Error in mutate(., ID = paste0(country, block, respondentID), BlockID = paste0(country, : could not find function &quot;mutate&quot;</p>
  </blockquote>
  <p>Even though Tidyverse is installed, checked library, etc. Is there something basic I'm missing?</p>
