Hello,
</div><div><br></div><div>I saw this question on SO yesterday: <a href="http://stackoverflow.com/questions/16877027/negative-number-of-rows-in-data-table-after-incorrect-use-of-set">http://stackoverflow.com/questions/16877027/negative-number-of-rows-in-data-table-after-incorrect-use-of-set</a></div><div><br></div><div>I think this is a bug in "set". But unfortunately, `set` calls for c-code internally and am not good at using gdb within R. Any ideas of what's the problem here? </div><div><br></div><div>Thanks,</div><div><div>Arun</div><div><br></div></div>
