I have a very dataset which I want to put in new dataframes according to date. Example: Suppose I have number day month hours 1 1 14 10 2 2 2 14 10 12 3 3 14 10 18 4 4 15 10 3 5 5 15 10 14 6 6 16 10 18 7 7 16 10 20 8 8 16 10 23 9 9 20 10 1 10 10 21 10 14 11 11 21 10 15 Now I want to get 5 new data frames, with first one number day month hours 1 1 14 10 2 2 2 14 10 12 3 3 14 10 18 etc. Is there an efficient way to do this?

thank you very much, I have a smaller question: If I give the first dataframe a name, say data1. How can I read it without pasting the dataframe -- View this message in context: http://r.789695.n4.nabble.com/putting-data-frame-values-in-new-dataframes-tp4655474p4655482.html Sent from the R help mailing list archive at Nabble.com.
Perhaps split(mydf, paste(mydf$month,mydf$day)) -- Don MacQueen Lawrence Livermore National Laboratory 7000 East Ave., L-627 Livermore, CA 94550 925-423-1062 On 1/14/13 5:57 AM, "condor" <radonnikodym at hotmail.nl> wrote:>I have a very dataset which I want to put in new dataframes according to >date.

Hi,
Do you want to read it from a saved file?
res<-split(dat1,dat1$day)
?res[[1]]
names(res)<-paste("data",1:5,sep="")
?write.table(res[[1]],file="data1.txt")
?read.table("data1.txt",sep="",header=TRUE)
#? number day month hours
#1????? 1? 14??? 10???? 2
#2????? 2? 14??? 10??? 12
#3????? 3? 14??? 10??? 18
A.K.

thank you very much, I have a smaller question:
If I give the first dataframe a name, say data1. How can I read it without
pasting the dataframe
