To add to Erik's answer:
You can use a three dimensional array
if all of your data for one cell is the
same type -- numeric presumably.
If the data were different types (numeric
and character, say), you could have a
matrix of mode list to do that. However,
that's unlikely to be worth the hassle.
'S Poetry' (found on www.burns-stat.com)
has a chapter on arrays that might be of
interest if you are using 3D arrays. I
think all of that chapter should apply to
R as well.

Hello,
from ?array
An array in R can have one, two or more dimensions. It is simply
a vector which is stored with additional attributes giving the
dimensions (attribute ‘"dim"’) and optionally names for those
dimensions (attribute ‘"dimnames"’).
A two-dimensional array is the same thing as a ‘matrix’.
So, to answer your question, "yes".

Hello everyone,
Could you please help me find out if R supports matrixes inside matrixes?
This is what I would like to do
I have an area map of humidity per km. I would like at every cell to
keep also information about the height of this area, the current
temperature etc.
Is something like that supported?
I would like to thank you in advance for your help
Best Regards
Alex
