Attached, you find a file.
I need for each (Materiale, tpdv, UM) to find sum,avg and count
My idea was to aggregate for the 3 parameters ..but I don t know how to get
the numeric value (SUM,COUNT,AVG) I need.
Can you help me?

get

?sum
?mean
?length

Aggregate works with one value only but you can try doBy package or 
split/lapply approach.
