applying a matrix function on subtables

[selmar]

Hello all

I have recently come across a new free software with table functions at stackoverflow.com:

http://finaquant.com/products/finaquantprotos

With the so called subtable transformer of this .net library it is possible to apply a table or matrix function on all subtables of an input table.

For more information see:

I am a proficient R user and I've never heard about such a construct before.

Is it possible to do this with R? Can you take a table as input and apply a matrix function on all of its subtables?
