Arguments

ann

A data.table of announcements. Must contain columns general_id, idcity, idesco_level_4, and xdata.

active_date

An IDate or Date cutoff: announcements with xdata >= active_date are flagged as active. Defaults to Sys.Date().

Value

A data.table with one row per general_id and columns: general_id, N (original row count), idcity (modal), idesco_level_4 (modal), attivo (1 if any row active, 0 otherwise).
