title: read.csv stops reading at row 523924 even thouhg the file has 799992 rows
body: <p>Any idea why R would stop reading the file before it gets to the end? </p>
  
  <p>I can open the file in excel, and it shows the full 799992. R reads only 65% of the file. I have saved the file as csv from Excel, but it did not change the number of rows R was able to read. In fact it stops reading at the exact same location every time.</p>
  
  <p>I use the following command.</p>
  
  <pre><code>lem1 &lt;- read.csv("lem1.csv", header=TRUE, sep =",")
  </code></pre>
  
  <p>I have the same issue on a similar data file, it only reads 57% of the file and stops "normally"</p>
