title: Correct number of decimal places reading in a .csv
body: <p>I have a .csv where one of the columns contains numbers that have 7 decimal places, e.g.: <code>-117.2403266</code>.</p>
  
  <p>When I'm reading the <code>.csv</code> into R it only ever shows 4 decimal places for that column, e.g.: <code>-117.2403</code>. Or maybe they are all there but when I print it only shows the four decimal places?</p>
  
  <p>I thought that this might be solved within the arguments of the <code>read.csv()</code> function, but it doesn't say anything about decimal places.</p>
