[R] multiple assignments ?

[r.ookie]

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)))

 [5,]    1
 [6,]    2

[10,]    2
[11,]    3
[12,]    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

Jim
