title: Wrong number of rows when reading a CSV file
body: <p>I have a CSV file that I wrote with a Perl script. Files opens fine in Excel or in Simple Text and looks fine. It has 9 rows. However, when I count it with nrow() or dim(), I get 8 rows. This is causing downstream problems. Headers are 'a' to 'j'. Thanks.</p>
