Hi listers, I could order a data that like this: x<-c(2,6,8,8,1) y<-c(1,6,3,5,4) o<-order(x) frame<-rbind(x,y)[,o] But, I would like to know if there is a way to order my data without setting up a data frame. I would like to keep independent vectors x and y. Any suggestions?

Hi Marcio, Is this what you want? x <- c(2,6,8,8,1) y <- c(1,6,3,5,4) o <- order(x) # If you want each vector order by x x[o] y[o] You can also use sort(), but then each vector would be sorted by itself, not both by x.

Suggestion: use the power of R. If x and y are independent then sorting y based on x is meaningless. If sorting y based on x is meaningful, then they are not independent. Trying to force non-independent things to pretend that they are independent just causes future headaches. Part of the great power of R is the ability to group things together that should be grouped. The wise learn this and use it (in some cases (mine) that wisdom comes at the expense of not having properly grouped in the past). Learn the power of with/within, data= arguments, and apply style functions, then you will be eager to combine things into data frames (or lists or ...) when appropriate. <<descend from soapbox>> -- Gregory (Greg) L.
