Dear R People:
Hello again!
I found something unusual in the behavior of the "endpoints" function
from the xts package:
> x1 <- ts(1:24,start=2008,freq=12)
> dat <- seq(as.Date("2008/01/01"),length=24,by="months")
> library(zoo);library(xts)
> x2 <- zoo(1:24,order=dat)
> #Here is the surprise:
> endpoints(as.xts(x1),'quarters')
[1] 0 1 4 7 10 13 16 19 22 24
> endpoints(as.xts(x2),'quarters')
[1] 0 3 6 9 12 15 18 21 24
Shouldn't the endpoints be the same, please? What am I doing wrong, please?
Thanks,
Erin
