In globalgov/messydates: A Flexible Class for Messy Dates

messydates 0.5.3

Components

• Improved year() to be faster and work on durations
• Improved precision()
• precision() is now a S3 generic, dispatching to precision.mdate()
• precision.mdate() now returns the inverse of the previous measure, meaning maximising precision makes more sense

messydates 0.5.2

Package

• Moved mreport() to {manydata}
• Consolidated and renamed scripts internally

Coerce to

• Fixed pkgdown#2855 by fixing how as_messydate methods interpret infinite dates
• Fixed time zone defaults in as.POSIXct.mdate() and as.POSIXlt.mdate()
• Fixed set bug in validate_messydate()

Coerce from

• Renamed as.numeric() to as.double() to fix S3 dispatching
• Separated extrema functions into min.mdate() and max.mdate() for summaries and vmin.mdate() and vmax.mdate() for vector coercion
• Separated tendency functions into mean.mdate(), median.mdate(), and modal.mdate() for summaries and vmean.mdate(), vmedian.mdate(), and vmodal.mdate() for vector coercion
• Vector coercion previously in random.mdate() now in vrandom.mdate()
• Improved how coercion/resolution functions handle BCE dates

Manipulation

• Fixed how precision() calculates precision

messydates 0.5.1

Package

• Fixed redirected url in README
• Fixed pkgdown help links

messydates 0.5.0

Package

• Dropped the vignettes as they were 'outdated'
• Dropped a number of tests to provide rapid testing framework
• Dropped {tibble} dependency by just using {dplyr}
• Updated Github workflows
• Updated testthat to version 3, tests now run in parallel
• Updated pkgdown to bootstrap 5
• Updated DESCRIPTION with config packages

Functions

• Moved from {stringr} to {stringi} for speed
• Added as.numeric.mdate() and as_messydate.numeric() for coercing between messydates and numbers (closes #85)
• Added seq.mdate() for creating sequences from one or two messydates
• This includes correct sequences for leap years and historical dates including before the common era
• Added is_bce() for testing whether dates are from before the common era
• Added stri_squish() helper for trimming white space everywhere
• Improved c.mdate() so that it will strip class from an mdate object, as expected
• Improved is_uncertain() and is_approximate() so that they also recognise % annotations
• Improved min.mdate(), max.mdate(), and modal.mdate() to avoid using expand() and consequently run much faster
• Improved min.mdate(), max.mdate(), modal.mdate(), mean.mdate(), median.mdate(), and random.mdate() by adding recursive argument for resolving vectors down to a scalar
• Fixed bug in messyduration.mdate() where the minimum of an underspecified later date was used
• Fixed bug in as_messydate() where zero padding for early dates was not added correctly

messydates 0.4.1

Package

messydates 0.4.0

Functions

• Closed #46 by adding the mdates_duration class that introduces methods to annotate a duration or period with representations of its uncertainty

• Closed #74 and #82 by adding other logical comparison operators for 'mdate' objects (e.g. <, >, <=, >=) (thanks @WerthPADOH)
• Closed #76 by adding proportional operators that calculate the proportion of messy dates meeting logical tests (e.g. %l% %le%, %g%, %ge%, %><%, %>=<%)
• Closed #77 by adding basic vector methods for subsetting and data frames (thanks @WerthPADOH)
• Added alias function mdate() for as_messydate()
• Renamed set family of functions to work as operators (i.e. %intersect% and %union%)
• Replaced is_element() by is_subset() for clarity and consistency
• Closed #80 by updating make_messydates() function to also construct ranges of dates
