I want to get the date sequence between a startDate
and endDate
by adding 1 month to the startDate
. ie, if startDate
is 2013-01-31 and endDate
is 2013-07-31, I would prefer to see dates like this:
"2013-01-31" "2013-02-28" "2013-03-31" "2013-04-30" "2013-05-31" "2013-06-30" "2013-07-31"
I have tried seq.Date(as.Date("2013-01-31"),by="month",length.out=7)
.
But the output of this code is like this
> seq.Date(as.Date("2013-01-31"),by="month",length.out=7)
[1] "2013-01-31" "2013-03-03" "2013-03-31" "2013-05-01" "2013-05-31" "2013-07-01" "2013-07-31"
So,what is the simplest solution to get the correct output?
I have to work with dates in R, and one of the most useful packages that I found for date data is lubridate
. For your problem, you can simply do the following:
require(lubridate)
# ymd function parses dates in year-month-day format
startDate <- ymd('2013-01-31')
# The %m+% adds months to dates without exceeding the last day
myDates <- startDate %m+% months(c(0:6))
lubridate
also has many other functions for dates, and I highly recommend taking a look.
