Convert date column to numeric and calculate its modulus with given timestep.

This function processes a date column in a data.table, converting it to a numeric representation and then computing the modulus with the provided timestep.

Usage

date_to_numeric_modulus(dt, date_column, timestep)

Arguments

dt

A data.table.

date_column

A character string representing the name of the date column in dt.

timestep

An integer representing the internal timestep.

Value

A modified data.table with two new columns: one for the numeric representation of the date minus the minimum date and another for its modulus with the timestep.
