The problem is that this doesn't seem to give what I want.  I did look
at this.  Perhaps doBy will work - haven't tried it yet.  But, any
the only thing we know what you want to do is aggregating data. 
That's why I directed you to the mentioned possibilities for data 
aggregating.

and doing what is recommended can help others to understand your 
problem. Without telling us anything we also can do almost nothing.
