title: Print, cat, paste in R separated by newline character
body: <p>I want to do the print the elements of a vector line by line in R like below</p>
  
  <p><code>1</code></p>
  
  <p><code>2</code></p>
  
  <p><code>3</code></p>
  
  <p>However, when I do <code>paste(c(1,2,3), "\n")</code> or <code>paste(c(1,2,3),sep = "\n")</code>, the new line never gets printed out. The same thing goes for <code>cat</code> as well. I always get the following:</p>
  
  <p><code>"1" "2" "3"</code></p>
  
  <p>I would like to know to get around this problem. </p>
