body: <p>How can I add double quotes to a string taken from a vector in R?</p>
  
  <p>I tried using paste but it doesn't work very well</p>
  
  <pre><code>kg_name=paste("\"",k_groups[i,],"\"")
  </code></pre>
  
  <p>lets say the value of k_groups[i,] is blah, so I'm looking for this result</p>
  
  <pre><code>"blah"
  </code></pre>
  
  <p>but the result is </p>
  
  <pre><code>"\" blah \""
  </code></pre>
