R: adding 1 month to a date

Question

I want to get the date sequence between a startDate and endDate by adding 1 month to the startDate. ie, if startDate is 2

Answer 1

This is not working, because R is not sure what to do with last day of the month :) So I have simple solution. Do the same but use 1st day of the next month and then substract 1:

    seq(as.Date("2013-02-1"),by="month",length.out=7)-1
[1] "2013-01-31" "2013-02-28" "2013-03-31" "2013-04-30" "2013-05-31" "2013-06-30" "2013-07-31"
