[R] Dimension of a vector

[maj at stats.waikato.ac.nz]

Consider the following:
> A <- 1:10
> A
 [1]  1  2  3  4  5  6  7  8  9 10
> dim(A)
NULL
> dim(A) <- c(2,5)
> A
     [,1] [,2] [,3] [,4] [,5]
[1,]    1    3    5    7    9
[2,]    2    4    6    8   10
> dim(A)
[1] 2 5
> dim(A) <- 10
> A
 [1]  1  2  3  4  5  6  7  8  9 10
> dim(A)
[1] 10

Would it not make sense to have dim(A) = length(A) for all vectors?
