Changes in version 1.4.0 (2025-11-12) The R package qs will be deprecated soon, so poems has updated its qs dependency to qs2. Please note that qs2 is not backward-compatible, so poems will no longer be able to handle qs data files. Changes in version 1.3.3 (2025-05-07) Bug fixes - Fixed a bug that caused the population_density function to fail when population density was logistic and there were no growth rates (that is, a stagnant population). - Fixed a bug in population_transitions in which excess survivals were "overdrawn" from populations that were already at zero. Changes in version 1.3.2 (2025-02-24) Bug fixes One of the tests for the ResultsManager object was failing on Fedora and Debian R-devel. This test has now been fixed. Changes in version 1.3.1 (2024-09-19) Bug fixes - poems no longer depends on geosphere. I am hopeful that this will clear up the test failures on CRAN's m1mac. Changes in version 1.3.0 Every update is an enhancement this time around: - Changed two of the vignettes to HTML vignettes. - These vignettes should now run much faster on CRAN servers. - Added a CONTRIBUTING.md file. - Added examples for all functions, classes, and data objects in the package. - Added a logo to the README. - poems is now documented compliant with srr standards G1.0 through G1.6. Changes in version 1.2.0 Bug fixes - The CRS of the tasmania_modifier raster dataset in /data has been changed from NA to the appropriate equal area projection. - The vignettes now handle the objects in /data appropriately. Enhancements - Test coverage has been increased for LatinHypercubeSampler.R, SimulationManager.R, and PopulationModel.R. - A CITATION file has been added. - A ![https://globalecologylab.github.io/poems/](pkgdown documentation site) has been added. - Code style has been improved across all R files and documentation. - The dataset documentation has been updated to keep up with the latest roxygen2 style. - Imports from the gdistance package are now more explicit. Changes in version 1.1.1 - Adjusted some tests so they will work correctly on certain Apple Silicon systems Changes in version 1.1.0 (2023-10-07) - Added density dependent dispersal, via density dependence in the source population and the target population - Added Poisson distributions as a possible parameter distribution to the Latin hypercube sampler Changes in version 1.0.6 - Patched some errors and notes that came up in the tests for the generator object and the spatial correlation object Changes in version 1.0.5 - added vignette for translocation/introduction of new populations Changes in version 1.0.2 (2022-01-17) Bug fixes - updated raster CRS strings in tests to avoid anticipated PROJ 8 errors #1 Enhancements - added method references in description Changes in version 1.0.1 (2021-03-29) - Initial public release
