Re: [R] Ordeing Zoo object
And how about if I want to order the series from the smallest to the largest value, keeping the date index in order to see when the values were predominantly negative etc...

[R] Ordeing Zoo object
Hi all, I would like to ask how to order a Zoo object? Consider following code dat - zooreg(rnorm(5), as.yearmon(as.Date(2001-01-01)), frequency=12) dat Jan 2001 Feb 2001 Mar 2001 Apr 2001 May 2001 -0.8916124 -0.4516505 1.1305884 -1.4881309 0.3703734 Here I want to order from last to 1st i.e. from May to Jan. So I used following code : dat[5:1] Jan 2001 Feb 2001 Mar 2001 Apr 2001 May 2001 -0.8916124 -0.4516505 1.1305884 -1.4881309 0.3703734 Therefore I am not getting what I desired. If someone points out the correct code I would be grateful.

If someone points out the correct code I would be grateful. The zoo object itself is always ordered by time. So it takes the observations you specified (5:1) and orders them by time again (so you get 1:5). You need to extract the data without the time index and then proceed as usual: sort(coredata(dat)) or coredata(dat)[5:1] etc. Z Thanks, -- View this message in context: http://n4.nabble.com/Ordeing-Zoo-object-tp955868p955868.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
