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().
