[R] sequential sum

Dear R users, I am trying to sum number that exist in another vector up to i, then increment i and repeat. Sorry. It's hard to explain but basically I am trying to do the following: test <- c(1,2,3,4); test2 <- c(3,5,6,7,2,8,8,4,4); test3 <- c(10,20,30,40); tmp <- 0; for (i in 1:length(test)){ tmp
