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

Perhaps simpler:
Hint: (seq_along(LETTERS) -1) %/% 5
## modular arithmetic can be useful for this sort of thing

Hi, Christofer,
try something along
len <- 5
split(Vec, rep(seq(ceiling(length(Vec)/len)), each = len))

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 vector, so looking for some efficient way
to achieve the same. Any pointer will be highly appreciated.
Thanks for your time.
