Re: [R] Ordering zoo-object by its index
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

Hello everyone,
Say I have zoo object
x.Date <- as.Date("2003-02-01") + c(1, 3, 7, 9, 14) - 1
x <- zoo(rnorm(5), x.Date)
y <- zoo(rt(5, df=2), x.Date)
z <- zoo(rt(5, df=5), x.Date)
Data <- merge(x,y,z)
What should I do to make the latest values appear at the top?
Thank you for your help!

Sergey

Re: [R] Ordering zoo-object by its index
One additional thought. If the reason you want to do that is
just so that you can see the last few rows more easily then
tail(Data)
will display the last few rows or tail(Data, 10) will display
the last 10 rows.

To display that object in reverse time order try this:
as.data.frame(Data)[nrow(Data):1, ]
