r - How to split a vector by delimiter?

Question

I have a vector of integer e.g. c(1,2,0,3,4) and I want 0 to be a delimiter and get list(c(1,2), c(3,4)). Is there any libary function I can use?

Answer 1

No library function I know of but you can write your own:

split.vec <- function(vec, sep = 0) {
    is.sep <- vec == sep
    split(vec[!is.sep], cumsum(is.sep)[!is.sep])
}

split.vec(c(1,2,0,3,4), 0)
# $`0`
# [1] 1 2
# 
# $`1`
# [1] 3 4
