title: Remove quotes from a character vector in R
body: <p>Suppose you have a character vector:</p>
  
  <pre><code>char &lt;- c("one", "two", "three")
  </code></pre>
  
  <p>When you make reference to an index value, you get the following:</p>
  
  <pre><code>&gt; char[1]
  [1] "one"
  </code></pre>
  
  <p>How can you strip off the quote marks from the return value to get the following?</p>
  
  <pre><code>[1] one
  </code></pre>
