extract_date: Extract the date from a charcter string

In reconhub/rfextras: Extra Functionalities for reportfactory

Description

This function is used to extract a date from a character vector, using a user-provided date parser. It first uses regular expressions to isolate potential dates from the character strings, and then applies the parser (by default, lubridate::ymd) to return a Date object. The function only handles dates provided as numbers.

Usage

extract_date(x, date_parser = lubridate::ymd)

Arguments

x	a character string containing dates to be extracted
date_parser	a function to extract dates from character strings; we recommend using lubridate's function there, e.g. ymd (any date format with year, month, day) or dmy (any format using day, month, year); defaults to lubridate::ymd
