[R] Importing and exporting threedimensional arrays

[Ferri Leberl]

Dear all,
 
I want to process a list of XML-Elements.
In one dimension the elements are listed; in the other their respective properties (name, comment, parent, children, attributes).
 
I am writing a script that processes such tables, and another one that produces sample tables to test the first script.
So the first script should import tabular-separated lists, and the second should export them with write.table (or anything better you suggest me).
 
As long as we stay two dimensional I see no difficulties.
 
However, there can be several children and several attributes. So my idea was to add a third dimension — but some tests I did showed me that e.g.
 
write.table(array(1:60,dim=c(4,3,5)),"beispielmatrix",sep="\t",quote=FALSE,row.names=F,col.names=F,dec=",")
 
produces a 2D-tsv.
 
So, how can I handle the fact, that there may be several items in a children resp. atrribute field?
 
Thank you in advance!
