version 1.4.0

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.

version 1.3.3

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.

version 1.3.2

Bug fixes

One of the tests for the ResultsManager object was failing on Fedora and Debian R-devel. This test has now been fixed.

version 1.3.1

Bug fixes

• poems no longer depends on geosphere. I am hopeful that this will clear up the test failures on CRAN’s m1mac.

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.

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 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.

version 1.1.1

• Adjusted some tests so they will work correctly on certain Apple Silicon systems

version 1.1.0

• 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

version 1.0.6

• Patched some errors and notes that came up in the tests for the generator object and the spatial correlation object

version 1.0.5

• added vignette for translocation/introduction of new populations

version 1.0.2

Bug fixes

• updated raster CRS strings in tests to avoid anticipated PROJ 8 errors #1

Enhancements

• added method references in description

version 1.0.1

• Initial public release
