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?
