Is there an easy way in R for me to itemize all valid days that occurred between two specified dates? For instance, I'd like the following inputs:
itemizeDates(startDate="12-30-11", endDate="1-4-12") To produce the following dates:
"12-30-11" "12-31-11", "1-1-12", "1-2-12", "1-3-12", "1-4-12" I'm flexible on classes and formatting of the dates, I just need an implementation of the concept.

We can get the dates between two dates with single method call using the dedicated datesUntil method of a LocalDate class. The datesUntill returns the sequentially ordered Stream of dates starting from the date object whose method is called to the date given as method argument.
You can use simple date arithmetic to find the number of days between two dates in Python. Define the 2 dates between which you want to find the difference in days. Then subtract these dates to get a timedelta object and examine the day's property of this object to get the required result.
To get all of the dates between 2 dates: Copied! function getDatesInRange(startDate, endDate) { const date = new Date(startDate. getTime()); const dates = []; while (date <= endDate) { dates.
You're looking for seq
> seq(as.Date("2011-12-30"), as.Date("2012-01-04"), by="days") [1] "2011-12-30" "2011-12-31" "2012-01-01" "2012-01-02" "2012-01-03" [6] "2012-01-04" Or, you can use :
> as.Date(as.Date("2011-12-30"):as.Date("2012-01-04"), origin="1970-01-01") [1] "2011-12-30" "2011-12-31" "2012-01-01" "2012-01-02" "2012-01-03" [6] "2012-01-04" Here's a function to meet your specific request
itemizeDates <- function(startDate="12-30-11", endDate="1-4-12", format="%m-%d-%y") { out <- seq(as.Date(startDate, format=format), as.Date(endDate, format=format), by="days") format(out, format) } > itemizeDates(startDate="12-30-11", endDate="1-4-12") [1] "12-30-11" "12-31-11" "01-01-12" "01-02-12" "01-03-12" "01-04-12" If you love us?
