title: How to display numeric columns in an R dataframe without scientific notation ('e+07')
body: <p>I have an R dataframe with one column containing a stringt of numbers but I would like to treat them as a factor (mainly to stop R shortening the numbers using e+04 etc...).  One way I have found to fix this problem is to edit the csv file the data is taken from, and add a dummy entry that has a word in the desired column and then reimporting it.  How do I get this effect using R functions without messing around with the csv?</p>
  
  <p>To clarify, my dataframe looks like this:</p>
  
  <pre><code>pNum,Condition,numberEntered
  1,2,5.0970304e+07
  </code></pre>
  
  <p>I want to change the data type of numberEntered from numeric to factor and get rid of the pesky e+07.</p>
