R help - Jan 2007 - accessing arrays

hi all. how can i adress a array directly. for example i wanna give array 1
other labels than array 2. How can I overcome this problem?

...this doesn't work

tab <- array(1:8, c(2, 2, 2))
dimnames(tab[,,1]) <- list(c("No","Yes"),
c("No","Yes"),c("ARRAY1"))
dimnames(tab[,,2]) <- list(c("big","small"),
c("small","big"),c("ARRAY2"))

try this :
x <- 
array(1:24,dim=c(2,3,4),dimnames=list(letters[1:2],LETTERS[1:3],letters[23:26]))

Cheers,
Wolfgang

You can't do that.  If you want to have different labels
on the first two dimensions, then a 3-dimensional array
doesn't seem to be the natural data structure.

I would suggest two matrices held in a list.
