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?

Thank for your help
