I would suggest that you use a list to store the values since it is
easier to create and reference:
> output <- list()
> for (i in 1:10) output[[i]] <- seq(i)
>
> output
[[1]]
[1] 1
[[2]]
[1] 1 2
[[3]]
[1] 1 2 3
[[4]]
[1] 1 2 3 4
[[5]]
[1] 1 2 3 4 5
[[6]]
[1] 1 2 3 4 5 6
[[7]]
[1] 1 2 3 4 5 6 7
[[8]]
[1] 1 2 3 4 5 6 7 8
[[9]]
[1] 1 2 3 4 5 6 7 8 9
[[10]]
[1] 1 2 3 4 5 6 7 8 9 10
