After sorting a dataframe by date

Ai...I see, i didn't know I can sort rowname.
more study to do :)

You deleted the context of this thread, but while you are looking at  
the rownames documentation you might also keep your eyes open for the  
zoo and xts packages which could convert to a matrix with the dates or  
date-times as rownames.

And you should learn to post in context. Nabble is NOT the way most  
people correspond on Rhelp. You will find that if you continue to  
flout local convention that people will begin to ignore your postings.
