calDDDsViaRxCui(
  df,
  RxCuiColName = RxCui,
  QuantityColName = Quantity,
  DaysSupply = DaysSupply,
  cores = 4
)

Arguments

df	data.frame, a drug ingredient`s ATC of the specific indication
RxCuiColName	a column name for RxCui of df
QuantityColName	a column name for drug quantity of df
DaysSupplyConName	a column name for the days that patient`s drug supplied of df

Value

A new data.table sample_data_subset_atc with following columns.

MemberId patient Id

DispenseDate patient`s drug dispensed date, and the time interval is from 2025-12-06 to 2038-01-25

NationalDrugCode drug NDC, total of 17,326 different drug codes
