I created an xts object using POSIXct from tick market data. ?I have used this before without problems, but for some reason today I am getting all NAs in my xts object. I had that problem before when I used package chron, but I am not using chron today. Other things that caused similar results in the past was when there was?inconsistencies?with?timezone?or the original start date was not defined. ?I recreated the data defining the timezone, ?and origin = "1970-01-01" but the issue was not resolved. When I run this code:?head(.index(myxts)) i get NA NA NA NA NA. ?I run it without the dot head(index(myxts)) and I get the same results, 5 NAs My understanding is that if you have an xts object, it must have an index made of time that is ordered. ?How can I have NAs then if class(myxts) shows xts

Hi Muhammad, It is nearly impossible to help if you do not provide a minimal, reproducible example that demonstrates this behavior. This post on Stackoverflow provides helpful instructions: http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example It would also help if you follow the "Surprising behavior and bugs" section of the posting guide: http://www.r-project.org/posting-guide.html Best, -- Joshua Ulrich | about.me/joshuaulrich FOSS Trading | www.fosstrading.com
