Hi, The unique function is easy to understand and use. Beyond that, I want to get also the frequency of repetition of each individual row in a data frame Let me explain with an example : x<-data.frame(a=c(1,2,3,1,2),b=c(2,3,4,2,3),c=c(10,20,30,10,20)) xu<-unique(x) We have, > x a b c 1 1 2 10 2 2 3 20 3 3 4 30 4 1 2 10 5 2 3 20 > xu a b c 1 1 2 10 2 2 3 20 3 3 4 30
I want to get the following data frame : a b c Freq 1 1 2 10 2 2 2 3 20 2 3 3 4 30 1 That is, in addition to the unique rows, I want to get the frequency of repetion of each individual row. I will appreciate all the help that I can get.
