Creating 2 week intervals (lubridate)
...m 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!
