kairos 2.4.0

Breaking changes

• The CountApportion class now inherits from TimeSeries (see aion).

New classes and methods

• Add start() and end() methods for AoristicSum and CountApportion.
• Add span() method for CountApportion.
• Add as.data.frame() method for CountApportion.

kairos 2.3.0 (2025-05-19)

Bugfixes & changes

• Deprecate simulate().

Enhancements

• bootstrap() method for MeanDate objects gained new interval, seed and rare arguments.

Breaking changes

• Fix bootstrap() method for MeanDate objects: revert the change introduced in v1.1.0. By default, bootstrap replicates are drawn from a multinomial distribution.

kairos 2.2.1 (2025-04-03)

Internals

• List aion in Depends.
• Update package metadata.

kairos 2.2.0 (2024-12-10)

New classes and methods

• Add as_seriation() to coerce objects to seriation orders.
• Add assess() to test the significance of seriation solutions (#4).
• Add density_event() and density_accumulation() to compute density estimates of event and accumulation dates.
• Add order_rows() and order_columns() to get permutation order.
• Add refine() to refine CA-based seriation.

Enhancements

• Translate into French.

Bugfixes & changes

• Fix a bug in predict_event() and predict_accumulation(): supplementary rows are no longer ignored.
• Fix calendar in jackknife() and bootstrap() methods for EventDate.
• Deprecate get_order() and seriate_refine().

kairos 2.1.1 (2024-07-26)

Internals

• Use latest dependencies.

kairos 2.1.0 (2024-02-26)

New classes and methods

• Add hist() methods.

Internals

• List dimensio in Depends.

kairos 2.0.2 (2023-11-27)

Internals

• Follow changes in dimensio v0.5.0.

kairos 2.0.1 (2023-09-05)

Bugfixes & changes

• Fix support for supplementary rows in event().

kairos 2.0.0 (2023-08-30)

New classes and methods

• Add image() methods.
• Add coef(), fitted(), residuals(), sigma() and terms() to extract values from EventDate objects.

Internals

• MeanDate, AoristicSum, RateOfChange and IncrementTest classes now inherit from TimeSeries (see aion).
• Use tinytest instead of testthat.

Bugfixes & changes

• Remove previously deprecated methods.

Breaking changes

• Use aion for internal date representation.
• Use graphics instead of ggplot2 to reduce hard dependencies (remove all autoplot() methods).
• For consistency, all mcd() methods now return a MeanDate object.

kairos 1.2.0 (2022-11-09)

New classes and methods

• Add seriate_refine() method for PermutationOrder objects.

Bugfixes & changes

• Deprecate refine().
• cutoff argument of event() is defunct (use rank instead).

kairos 1.1.0 (2022-06-18)

New classes and methods

• Add seriation methods: seriate_rank(), seriate_average(), permute(), get_order().
• Add SimulationMeanDate to store mean date estimations from simulated assemblages.
• Add simulate() method for MeanDate objects.

Breaking changes

• No longer use classes from arkhe.
• Fix bootstrap() method for MeanDate objects: resample with replacement instead of simulating observations from a multinomial distribution.

kairos 1.0.1 (2022-03-11)

Bugfixes & changes

• Fix aoristic sum calculation (#1). aoristic() now calculates weights within the time blocks rather than at the break dates between blocks.

kairos 1.0.0 (2021-11-08)

• First release.
