Hi again, Happy new year 2014 to every R gurus and users.
I am struggling with some calculation with dates... Let say I have following vector of months: Months <- c("Jan", "Dec", "Mar") Now I need to assign year with them. This assignment will be based on some given date. Let say my given date is : Given_Date <- as.Date("2013-12-23") So in this case, the modified month will be: Months_Mod <- c("Jan-2014", "Dec-2013", "Mar-2014") However if given date is: Given_Date <- as.Date("2014-01-04") then the modified months will be: Months_Mod <- c("Jan-2014", "Dec-2014", "Mar-2014") My problem is that, I can not extablish some logic around it, so that I can do it programmatically for any Month-vector and for any Given-date. Can someone help me to accomplice this?
