Package: lacunr Type: Package Title: Fast 3D Lacunarity for Voxel Data Version: 1.0.2 Date: 2025-08-27 Authors@R: c( person("Elliott", "Smeds", , "elliott.alfred93@gmail.com", role = c("aut", "cre", "cph"), comment = c(ORCID = "0000-0003-1054-7491")), person("J. Antonio", "Guzmán Q.", role = "cph", comment = "Author of original version of voxelize() function") ) URL: https://github.com/ElliottSmeds/lacunr BugReports: https://github.com/ElliottSmeds/lacunr/issues Description: Calculates 3D lacunarity from voxel data. It is designed for use with point clouds generated from Light Detection And Ranging (LiDAR) scans in order to measure the spatial heterogeneity of 3-dimensional structures such as forest stands. It provides fast 'C++' functions to efficiently bin point cloud data into voxels and calculate lacunarity using different variants of the gliding-box algorithm originated by Allain & Cloitre (1991) .
