Thanks for the hint with the "dimnames". I found a rather similar problem in
the mailing list solved like this:
x <- matrix(1:4,2)
y <- matrix(5:8,2)
z <- list(x,y)
nm <- c("a","b")
nms <- list(nm,nm)
z <- lapply(z,function(x){
dimnames(x)<-nms
x
})
Is there anything wrong using a list instead of an array???

Hi,
If all your matrices have the same size, you should work with an array
and not with a list. Then you can use dimnames to set the names of the
rows, columns, and so on..

Hello,
I have another stupid question. I hope you can give me a hint how to
solve this:
I have a list and one element is again a list containing matrices, all
of the same dimensions. Now, I'd like to set the dimnames for all
matrices:
example code:
m1 <- matrix(1:25, nrow=5)
m2 <- matrix(26:50, nrow=5)
# ... there can be much more than two matrices
l <- list()
l[[1]] <- list(m1,m2)
r_names <- LETTERS[1:5]
c_names <- LETTERS[6:10]
? how can I apply these names to any number of matrices within this
list-list ?
Ciao,
Antje
