Hello,
Perhaps I am missing something here about the function structure() (Platfrm etc.
in the end?

Nope. You're missing something about the ":" operator
1:3 == c(1,2,3)
3:1 == c(3,2,1)

dim=3:1 means you want this as a 3x2x1 array, 6 cells in total, but 3 data.
1x2x3-array...
2:2 = from 2 to 2 step 1 = 2

2-array, four values
1x2x3x4 array, 24 cells, four values.
