[R] re ferring to a group of vectors without explicit enumeration

[jim holtman]

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
