I'm attempting to sort a 3 dimensional array that looks like this
> x
, , 1
     [,1] [,2]
[1,]    9    9
[2,]    7    9
, , 2
     [,1] [,2]
[1,]    6    5
[2,]    4    6
, , 3
     [,1] [,2]
[1,]    2    1
[2,]    3    2

Such that it ends up like this ....
> y
, , 1
     [,1] [,2]
[1,]    2    1
[2,]    3    2
, , 2
     [,1] [,2]
[1,]    6    5
[2,]    4    6
, , 3
     [,1] [,2]
[1,]    9    9
[2,]    7    9

I think this is sorting across the third dimension but several attempts using either the sort or apply functions have not worked.  Any and all suggestions most welcome.  Thanks
