incidence2 1.2.3 Unreleased

New functions

  • Reintroduces the cumulate() functionality (previously deprecated in 1.2.0).

Breaking changes

incidence2 1.2.2 2021-08-23

Bug fixes

  • Fixes bug when input object to incidence is a data.table.

incidence2 1.2.1 2021-07-14

Bug fixes

  • Fixes bug in incidence() when more than one column was given for the date_index.
  • Fixes incorrect test that did not take in to account changing time zones.

incidence2 1.2.0 2021-07-07

New functions

  • new_incidence(): A minimal incidence constructor.
  • validate_incidence(): Check for internal consistency of incidence-like object.
  • build_incidence(): Allows you to construct an incidence object whilst specifying your own date grouping function.
  • format.incidence()

Deprecated functions

  • cumulate() will now give a deprecation error. We have removed the function to avoid users erroneously regressing against a cumulative count.

Bug fixes

  • Fixes bug in incidence() when dates were a character vector and the the default, daily, interval was specified.

Other updates

  • Now uses dplyr to handle list based columns (e.g. record-type objects from vctrs). For data.frames with only atomic columns, data.table is still used.
  • Printing and summaries of incidence objects have been improved to remove duplication in the overview section.

incidence2 1.1.0 Unreleased

  • New function complete_counts().
  • plot() and facet_plot() now have a centre_dates argument which can be set to FALSE to get histogram-esque date labels for single month, quarter and yearweek groupings.
  • Internal refactoring due to breakages changes in the upstream grates package.

incidence2 1.0.0 2021-03-30

Due to multiple changes in the underlying representation of incidence2 objects this release may possibly break old workflows particularly those relying on the old implementations of date grouping:

  • Now uses the package grates for date grouping. This introduces the s3 classes yrwk, yrmon, yrqtr, yr, period and int_period as well as associated constructors which incidence now builds upon. As a result of this the aweek dependency has been dropped.
  • Add’s keep_first and keep_last functions.
  • Construction of incidence objects now faster due to underlying use of data.table.

incidence2 0.2.2 2020-11-12

  • Fixes bug in get_interval.
  • Removes message that was displayed when incidence class dropped.
  • Refactoring of internal code to improve maintainability.
  • Tests now use the 3rd edition of testthat.

incidence2 0.2.1 2020-10-16

  • Fixes bug in
  • Limits internal reliance on dplyr.

incidence2 0.2.0 2020-09-22

  • Fixes issue with monthly incidence objects when show_cases = TRUE (see #42).
  • Additional checks added for assessing whether a manipulated incidence object maintains its class.
  • Improved implementation speed.
  • NA’s now ignored in the count variable of a pre-aggregated input to incidence function.
  • Fixes axis labelling and spacing.

incidence2 0.1.0 2020-09-07

  • Initial release.
