fix_date: Convert improperly formatted date to R's Date class

In nathansam/datefixR: Standardize Dates in Different Formats or with Missing Data

Convert improperly formatted date to R's Date class

Description

Converts a single improperly formatted date to R's Date class. Supports numerous separators including /,- or white space. Supports all-numeric, abbreviation or long-hand month notation. Where day of the month has not been supplied, the first day of the month is imputed. Either DMY or YMD is assumed by default. However, the US system of MDY is supported via the format argument.

Usage

fix_date(date, day.impute = 1, month.impute = 7, format = "dmy")

Arguments

date	Character to be converted to R's date class.
day.impute	Integer. Day of the month to be imputed if not available. defaults to 1. If day.impute = NA then NA will be imputed for the date instead and a warning will be raised. If day.impute = NULL then instead of imputing the day of the month, the function will fail
month.impute	Integer. Month to be be imputed if not available. Defaults to 7 (July). If month.impute = NA then NA will be imputed for the date instead and a warning will be raised. If month.impute = NULL then instead of imputing the month, the function will fail.
format	Character. The format which a date is mostly likely to be given in. Either "dmy" (default) or "mdy". If year appears to have been given first, then YMD is assumed for the subject (format argument is not used for these observations)

Value

An object belonging to R's built in Date class.
