<DIV><FONT face=Arial size=2>Dear all,</FONT></DIV>
<DIV><FONT face=Arial size=2>Sorry for the simplicity of the question, but how
does one go about removing duplicated rows in a data.frame?</FONT></DIV>
<DIV><FONT face=Arial size=2>I'm looking for a quick and
simple solution, as my data.frames are relatively large (50000 by 50). I've
racked my brain and searched the help files and found nothing useful or quick,
</FONT><FONT face=Arial size=2>only duplicated() and unique() which work only
work on lists.</FONT></DIV>
<DIV><FONT face=Arial size=2>Thanks</FONT></DIV>
<DIV><FONT face=Arial size=2>Gary.</FONT></DIV>
