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
