R help - Oct 2011 - about the array transpose

Hi, all,

I am a newbie for [R]
Would anyone help me how to transpose a 3x3x3 array for 1:27

Eg.
A<-array(1:27, c(3,3,3)

What is the logic to transpose it to B<-aperm(A, c(3,2,1))

Because I found I could not imagine how it transposes, anyone could solve my
problem?
And most important I could get the number what I expected, I think if I
could not figure it out, I will have a confused concept which will affect my
future learning of 3D models in [R].

Highly appreciated and thanks.

VD

It simply says third dimension first, second second, and first third.
