Re: [R] Partition a vector into select groups with fixed length

Hello, Bert's modular arithmetic way simplifies my code a lot. breakVec <- function(x, n = 5){ if(n < 1) stop(paste("Illegal value n:", n)) f <- if(n == 1) "" else (seq_along(x) - 1) %/% n split(x, f) } Hope this helps, Rui Barradas Às 20:08 de 18/08/19, Bert Gunter escreveu: Perhaps

Perhaps simpler: Hint: (seq_along(LETTERS) -1) %/% 5 ## modular arithmetic can be useful for this sort of thing Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley Breathed in his "Bloom County" comic strip ) O

Hi, Christofer, try something along len <- 5 split(Vec, rep(seq(ceiling(length(Vec)/len)), each = len)) Hth -- Gerrit - Dr. Gerrit Eichner Mathematical Institute, Room 212 gerrit.eich...@math.uni-giessen.d

Hello, The following function will do it. It uses a standard cumsum trick to create a break vector f. And predicts special cases (n = 0 or n = 1). breakVec <- function(x, n = 5){ if(n < 1) stop(paste("Illegal value n:", n)) if(n == 1){ f = "" }else{ f <- c(1, rep(0, n - 1)) f <

Hi, Let say I have a vector as below Vec = LETTERS Now I want to break this vector into groups of the same length of 5. So, 1st group consists - "A" "B" "C" "D" "E" 2nd group - "F" "G" "H" "I" "J" and so on.. last group will consist only the leftover elements I have a very large initial vecto
