Function reference • messydates

Coerce to These functions construct and/or coerce dates to the `mdate` class:
`new_messydate()` `validate_messydate()`	A flexible date class for messy dates
`as_messydate()` `mdate()` `make_messydate()`	Coercion from regular date classes to mdate
`on_or_before()` `on_or_after()` `as_approximate()` `as_uncertain()`	Annotates dates as censored, uncertain, or approximate
`new_messyduration()` `messyduration()` `validate_messyduration()`	A duration class for mdates
Coerce from These functions coerce dates from the `mdate` class into a single `Date`:
`as.Date(<mdate>)` `as.POSIXct(<mdate>)` `as.POSIXlt(<mdate>)`	Coercion from messy dates
`min(<mdate>)` `max(<mdate>)` `median(<mdate>)` `mean(<mdate>)` `modal()` `random()`	Resolves messy dates into a single value
Manipulation These functions expand or contract objects of `mdate` class from/into a list:
`expand()`	Expand messy dates to lists of dates
`contract()`	Contract lists of dates into messy dates
Operations These methods help operate on objects of the `mdate` class:
`+`(<mdate>) `-`(<mdate>)	Arithmetic operations for messydates
`%intersect%` `%union%`	Set operations for messy dates
`is_messydate()` `is_intersecting()` `is_subset()` `is_similar()` `is_precise()` `is_uncertain()` `is_approximate()` `<`(<mdate>) `>`(<mdate>) `<=`(<mdate>) `>=`(<mdate>)	Logical tests on messy dates
`year()` `month()` `day()` `precision()`	Extracting components from messy dates
`%l%` `%g%` `%ge%` `%le%` `%><%` `%>=<%`	Proportion of messy dates meeting logical test
Data Working with ‘messy’ data:
`mreport()`	Data report for datasets with 'mdate' variables
`battles`	Dates of battles in 2001
