title: Prevent as.character from using exponential notation r
body: <p>Is there a way to prevent <code>as.character</code> from using exponential notation? For example, I have</p>
  
  <pre><code>num &lt;- c(9999999, 10000000)
  char &lt;- as.character(num)
  char
  [1] "9999999" "1e+07"
  </code></pre>
  
  <p>But instead I would like to have <code>char</code> be <code>"9999999" "10000000"</code>. Thanks!</p>
