Do you mean something like this?
>
n <- 5
>
(vec1 <- matrix(rep(1, n)))
[,1]
[1,] 1
[2,] 1
[3,] 1
[4,] 1
[5,] 1
>
(vec2 <- matrix(rep(2, n)))
[,1]
[1,] 2
[2,] 2
[3,] 2
[4,] 2
[5,] 2
>
(vec3 <- matrix(rep(3, n)))
[,1]
[1,] 3
[2,] 3
[3,] 3
[4,] 3
[5,] 3
>
>
(vec <- matrix(c(vec1, vec2, vec3)))
[,1]
[1,] 1
[2,] 1
[3,] 1
[4,] 1
[5,] 1
[6,] 2
[7,] 2
[8,] 2
[9,] 2
[10,] 2
[11,] 3
[12,] 3
[13,] 3

Simple one, have read and googled, still no luck!
I want to create several empty vectors all of the same length.
I would like multiple empty vectors (vec1, vec2, vec3) and want to create them
all in one line.
I've tried
vec1,vec2,vec3 <- vector(length=5)
and
c(vec1,vec2,vec3) <- vector(length=5)
and several other attempts but nothing seems to work ... suggestions?
Thanks
