Hello. the rep(x) function replicates the vector x. I am looking for a quick way of "expanding" a vector. Here is what I mean by "expand": given: x<-c(2,5,4) If I "expand" x three times, then I will get 2,2,2,5,5,5,4,4,4. In other words, I want to keep the original ordering (2,5,4) but duplicate each of the original entries three times. Is there such a function? If not, can someone suggest a fast way of doing this? Thanks.
