[R] About 5.1 Arrays

[Stephen Liu]

Hi Gerrit,

Thanks for your advice.



- snip -

> A[i, j, k] is the value of the element in position (i,j,k) of array A. In 
> other words, it is the entry in row i, column j, and "layer" k (if one 
> wants to think of A as a cuboidal grid).

Sorry I can't follow.  Could you pls explain in more detail.

e.g.

> z <- 0:23
> dim(z) <- c(3,4,2)
> dim(z)
[1] 3 4 2


> z
, , 1

     [,1] [,2] [,3] [,4]
[1,]    0    3    6    9
[2,]    1    4    7   10
[3,]    2    5    8   11

, , 2

     [,1] [,2] [,3] [,4]
[1,]   12   15   18   21
[2,]   13   16   19   22
[3,]   14   17   20   23


TIA
