Hi all, I know this is easy, but I really do not have any idea to solve it.
I have this kind of data set: dat <- read.table(text="Day Year Jan Feb Mar Apr 1 2012 0 2.5 0.5 2 2 2012 0 6.5 0 29 3 2012 0 9.5 0 0 4 2012 0 0 8 0.5 5 2012 0 5 0.5 110.5 6 2012 0 4 3.5 22 7 2012 11 0 12.5 3.5 8 2012 0 5 8 36.5 1 2013 0 2.5 0.5 2 2 2013 0 6.5 0 29 3 2013 0 9.5 0 0 4 2013 0 0 8 0.5 5 2013 0 5 0.5 110.5 6 2013 0 4 3.5 22 7 2013 11 0 12.5 3.5 8 2013 0 5 8 36.5",sep="",header=TRUE) and I want it to be in this form: Year Day Month Amount 2012 1 1 0 2012 2 1 0 2012 3 1 0 2012 4 1 0 2012 5 1 0 2012 6 1 0 2012 7 1 11 2012 8 1 0 2012 1 2 2.5 2012 2 2 6.5 2012 3 2 9.5 2012 4 2 0 2012 5 2 5 2012 6 2 4 2012 7 2 0 2012 8 2 5 2012 1 3 0.5 2012 2 3 0 2012 3 3 0 2012 4 3 8 2012 5 3 0.5 2012 6 3 3.5 2012 7 3 12.5 2012 8 3 8 2012 1 4 2 2012 2 4 29 2012 3 4 0 2012 4 4 0.5 2012 5 4 110.5 2012 6 4 22 2012 7 4 3.5 2012 8 4 36.5 2013 1 1 0 2013 2 1 0 2013 3 1 0 2013 4 1 0 2013 5 1 0 2013 6 1 0 2013 7 1 11 2013 8 1 0 2013 1 2 2.5 2013 2 2 6.5 2013 3 2 9.5 2013 4 2 0 2013 5 2 5 2013 6 2 4 2013 7 2 0 2013 8 2 5 2013 1 3 0.5 2013 2 3 0 2013 3 3 0 2013 4 3 8 2013 5 3 0.5 2013 6 3 3.5 2013 7 3 12.5 2013 8 3 8 2012 1 4 2 2012 2 4 29 2012 3 4 0 2012 4 4 0.5 2012 5 4 110.5 2012 6 4 22 2012 7 4 3.5 2012 8 4 36.5 2013 1 4 2 2013 2 4 29 2013 3 4 0 2013 4 4 0.5 2013 5 4 110.5 2013 6 4 22 2013 7 4 3.5 2013 8 4 36.5 I want to rearrange the data according to the YEAR (year by year) Thank you.
