lacunr 1.0.2 (Release date: 2025-08-27)

Improvements:

• The tutorial vignette lacunr-tutorial.Rmd has been edited to clarify the relationship between raw lacunarity and the proportion of occupied space.
• External package anchors have been added to function documentation, per CRAN guidelines.
• The test suite now covers the periodic boundary algorithm.
• Fixed broken URLs.
• Package now has a CITATION file.

lacunr 1.0.1 (Release date: 2024-06-03)

New features:

• New plotting functions lac_plot(), lacnorm_plot(), and hr_plot() now let users conveniently plot lacunarity or H(r) curves returned by lacunarity().
• Package now has a sample LiDAR dataset, glassfire.
• Package now includes tutorial vignettes.
• Package now has a working test suite.

Improvements:

• Package is now set up for CI via Github Actions.
• Minor tweaks to lacunarity():
  • The periodic argument now has improved error handling.
  • The underlying C++ function received a minor change to simplify how it calculates lacunarity at the smallest box size. This shouldn’t alter the output.
• Improvements to error handling of bounding_box() and voxelize().
• Removed C++11 requirement from Makevars[.win] to make the package compatible with R version 4.3. This may cause issues building the package with R versions <= 3.5 on systems with very old compilers.
• Various bug fixes in the package documentation to satisfy R CMD check — mainly issues involving formatting of DOIs and removing broken URLs.

lacunr 0.2.0 (Release date: 2024-03-11)

New features:

• New function pad_array() added.
• lacunarity() now computes H(r) curves in addition to lacunarity values.

lacunr 0.1.1 (Release date: 2023-12-11)

Initial public launch

• Core functions voxelize(), bounding_box(), and lacunarity() implemented.
• bounding_box() includes S3 method for lasmetrics3d class created by lidR::voxel_metrics(), as well as lacunr’s native lac_voxels class created by voxelize().
