title: RGB to Hex converter
body: <p>Suppose I have this vector</p>
  
  <pre><code>x &lt;- c("165 239 210", "111 45 93")
  </code></pre>
  
  <p>Is there a neat package to convert RGB values to hex values in R? I found many javascript ways but not one for R.</p>
  
  <pre><code>x &lt;- "#A5EFD2" "#6F2D5D"
  </code></pre>
