title: Creating a comma separated vector
body: <p>I have a numeric vector, one, which I'm trying to turn into a character vector where 
  each element is separated by commas.</p>
  
  <pre><code>&gt; one = c(1:5)
  &gt; paste(as.character(one), collapse=", ")
  [1] "1, 2, 3, 4, 5"
  &gt; paste(as.character(one), sep="' '", collapse=", ")
  [1] "1, 2, 3, 4, 5"
  </code></pre>
  
  <p>However, I want the output to look like:</p>
  
  <pre><code>"1", "2", "3", "4", "5" 
  </code></pre>
  
  <p>Am I missing some parameter from the paste function?
  Help!?</p>
