[R] how to write and read an array ?

[vincent@7d4.com]

Hi,
Apologies if the question is too simple
but I didn't find the answer by myself.

I'm able to create a 3-dimensionnal array A
and to write it with write.table()
... but, after that, I don't find how to read it
with read.table() getting the right 3 dimensions.

I tried to use as.array(), to force the dim, etc
but it didn't work.
(It's probably obvious ... ?)

Thanks for your info or pointer.
Vincent
