title: R: Paste two strings without space
body: <p>I want to merge following two strings in <code>R</code> (and remove the spaces). I was using <code>paste</code> but I was not able to get desired results.</p>
  
  <pre><code>a &lt;- "big earth"
  b &lt;- "small moon"
  
  c &lt;- paste(a,b, sep = "")
  </code></pre>
  
  <p>I want to have a <code>c &lt;- "bigearthsmallmoon"</code>
  Thank you very much for the help.</p>
