check_if_year_month_day_entered

Check if a vector contains a complete date

Provides tools for converting and imputing date values to the ISO 8601
standard format and for reconciling differences between two versions of a
data set. The package automatically detects date patterns within data
frame columns and converts them to consistent ISO-formatted dates, with
optional imputation of missing day or month components based on
user-defined rules. It also includes functionality to identify inserted,
deleted, and updated records, as well as column- and value-level changes,
when comparing old and new versions of a data frame. Only one date format
may be applied within a single column.
