[R] PROC TABULATE with R

[David Meyer]

You can also have a look at structable() in vcd, especially the indexing 
functions. The problem with OLAP in R is, that you will have to create 
sth. like a hierarchical factor to handle rollup/drilldown correctly.

And you will have to decide whether it's purely memory-based (fast 
calculations, but memory limit), or you do it using data bases / SQL (slow).

And finally, you will need some simple GUI to provide interactive use 
(doing OLAP using command-line functions is not really OLAP).

Best,
David
