[R] Importing and exporting threedimensional arrays

Thanks for your answer.
I'm afraid it doesn't.
The planned workflow should be:
Somebody delivers me a table containing the essential relations of an XML-schema in form of a list that should, once it is functional, be generated out of R. So I need a form that is as universal as possible — therefore I thought of a tabular separated list.
If I make an array:


save it


and read it in the bash

cat feld

I receive

     @Q��z���,9�  !��w�?,��3c[�/g�2mSD4ѡ鄆��C��r�>�#�'�]劸���?P5�a��(b�#�$RH#�,rȣ�"J(��*j���&Zh��.z�c�!F▒c�)f�c
So I guess it will be a science of its own to understand, how the file is structured.

So I need either a format that allows to easily parse the import 3D-Matrix outside R, or I need any good idea how to avoid the third dimension (e.g., might it function to use a second separation character within the collumns which may contain several items?

Thank you in advance!
Have a pleasant weekend.
Yours, Ferri

You can save 3D objects (or objects of any form or shape) by using ?save.
You would then retrieve them with ?load.

Hope this helps,
