title: How to obtain scientific notation in R output
body: <p>This may be an old question but I am unable to get a solution. </p>
  
  <p>I have the following sequence of numbers</p>
  
  <pre><code>  sequence1&lt;-c(1,.5, .025,10,230,.006,.11)
  </code></pre>
  
  <p>Is there a way to convert these into scientific notation such that the output is </p>
  
  <pre><code>  "1"        "5*10^-2"  "1*10"       "2.3*10^2"    "6*10^-3"  "1.1*10-1".
  </code></pre>
  
  <p>I am unable to find a function but have looked all over</p>
