[R] accessing arrays

[Lars Rohrschneider]

Hi Wolfgang,

thanks for your hint. But I am desperating. I have an 3 dim array of say 10
matrices where every matrix has to stick an other label. I found no way to
direct assign the labels.

for example 

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

should look like this
, , 1

    No Yes
No   1   3
Yes  2   4

, , 2

        big  small
small   5   7
big     6   8
