[R] arrange data

[arun]

HI,

I think it would be better to store this as a list.
For example:


list1<- list(kuantan.dt[kuantan.dt[,2]==11,],kuantan.dt[kuantan.dt[,2]==12,])


If you wanted to delete 31 December and do column bind:
res<-cbind(kuantan.dt[kuantan.dt[,2]==11,], kuantan.dt[kuantan.dt[,2]==12 & kuantan.dt[,3]!=31,]) # assuming 3rd column corresponds to day



A.K.

Subject: [R] arrange data

Dear r-users,
 
I have daily rainfall data from 1971 to 2000.  I would like to extract november and december data only.  I would also like to do column bind for november and december, therefore I would like to delete 31 December from december data so that the length of november and december are the same.  Hope somebody can help me.  I tried this below:
 
> kuantan.dt.1 <- kuantan.dt[(kuantan.dt$Bulan >=11) & (kuantan.dt$Bulan <= 12),]
> head(kuantan.dt.1) ; tail(kuantan.dt.1)
