HI Dila, You have to order it afterwards. res <- transform(melt(dat,id.var=c("Year","Day")),Month=match(variable,month.abb),Amount=value)[,-c(3:4)]
res1 <- res[with(res,order(Year,Month,Day)),] A.K. On Friday, February 28, 2014 2:16 AM, dila radi <dilarad...@gmail.com> wrote: Dear Arun, Thank you so much for your concern. It is slightly differ from what I want after I applied it on my data. My bad... It works by rearranging the data month by month.

I meant 2012 (Jan-April) followed by 2013 (Jan - April) Your help is really helpful, but I have to do some alteration which is I stuck in rearranging it year by year.
