datefixR - Standardize Dates in Different Formats or with Missing Data
There are many different formats dates are commonly
represented with: the order of day, month, or year can differ,
different separators ("-", "/", or whitespace) can be used,
months can be numerical, names, or abbreviations and year given
as two digits or four. 'datefixR' takes dates in all these
different formats and converts them to R's built-in date class.
If 'datefixR' cannot standardize a date, such as because it is
too malformed, then the user is told which date cannot be
standardized and the corresponding ID for the row. 'datefixR'
also allows the imputation of missing days and months with
user-controlled behavior.
