Hi everyone,I have a data daily data (x) for 10 years starting from
04-01-1995 to 03-31-2005.
I was able to get the yearly sum for the ten years using
aggregate(x, years, sum).
But this gave me the yearly sum for 1995 (Apr- Dec); 1996 (Jan-Dec)
---------2005 (Jan-Mar).
But I want to get the aggregates for Apr-1995 to Mar 1996, Apr 1996- mar
1997 and so on.

your help will be higly appreciated.
Thanks in advance
