[R] Ordering zoo-object by its index

[Sergey Goriatchev]

Hi, Gabor

Yes, I am familiar with tail() function. I use it extensively on a day
to day basis.
In this particular case I needed to order a zoo object by date, after
I have created it with RBloomberg.

Thank you for your time!

Regards,
Sergey
