Hello,
I have a list of dates in which I am going use for a time series analysis. I
want to break these dates up into 2 week intervals and count the number of
times a date appears in this interval.
For example from Nov. 19, 2000 to Dec 2 ,2000 with the data listed below I want
to return
Start_date Count2000/11/19 4
Date: 2000/11/20 2000/11/21 2000/11/19 2000/11/29
My first approach was toa vector of the two week time periods (like below) and
then match my dates with the intervals. But this did not work.
DataInterval<-rep(NA, 316)
TwoWeekint<-function(date) { for (i in 1:316) new.day<-i*14
DataInterval[i]<-as.interval(new_period(days=new.day), ymd("2000-11-17"))
}
Thanks!
