title: How to print a character list from A to Z?
body: <p>In R, how can I print a character list from A to Z?  With integers I can say:</p>
  
  <pre><code>my_list = c(1:10)
  &gt; my_list
   [1]  1  2  3  4  5  6  7  8  9 10
  </code></pre>
  
  <p>But can I do the same with characters?  e.g. </p>
  
  <pre><code>my_char_list = c(A:Z)
  my_char_list = c("A":"Z")
  </code></pre>
  
  <p>These don't work, I want the output to be: <code>"A" "B" "C" "D"</code>, or separated by commas.</p>
