infer_holiday: Infer if a date is a fedral holiday

In featurizer: Some Helper Functions that Help Create Features from Data

Description

A function that returns the federal holiday observed on a given date. If there was no holiday observed, it returns None. The function takes in a list of dates, where each date is in the format YYYY-MM-DD and checks them against a database of federal holidays (2012-2020). It returns the holiday that was/will be observed on the date. If no holiday is observed on that date, it returns "None" corresponding to that date. This computation happens in parallel and hence is very fast.

Usage

infer_holiday(date_lst, detect_cores)

Arguments

date_lst	a list of dates strings of the format YYYY-MM-DD
detect_cores	If False (default), 2 cores are used. If True, half the number of cores are used on Mac OS else 2 cores are used.

Value

Returns the kind of fedral holiday that was/will be observed on that date. If there was no holiday observed, it returns None. It does the lookup in parallel and hence is very fast.

Examples

infer_holiday(date_lst = c("2020-12-25", "2020-09-07", "2020-09-08", "2016-01-18",
 "2016-01-19", "2016-01-15"))
