New insights into the stone tool-making behaviors of Homo floresiensis and Homo sapiens at Liang Bua

Dataset and R code for reproducing figures and statistical results in 'New insights into the stone tool-making behaviors of Homo floresiensis and Homo sapiens at Liang Bua', by Lin et al. V3. Update log: Included detailed stratigraphic illustrations to compliment the 'Artifact sampling' section in Supplementary Information. This version of the dataset incorporates a more robust measure of bulb angle derived from a vector-based measurement method. Relative to the bulb angle measurements used in earlier versions that were calculated using the MeshLab Virtual Goniometer plugin (Yezzi-Woodley et al. 2020), this approach produces a stronger statistical relationship with the expected covariate of flake fracture plane angle (see Lin et al. 2025). It also provides greater explanatory power for accounting for variation in complete flake weight (see Li et al. 2022).用于复现《弗洛勒斯人（Homo floresiensis）与智人（Homo sapiens）梁布亚遗址石器制作行为新认知》（Lin等）一文中图表与统计结果的数据集与R代码 V3. 更新日志： 补充了详细的地层图解，以完善补充材料中的“石器标本采样”章节。 本版数据集采用了基于矢量的测量方法推导得到的更可靠的打击泡角度（bulb angle）测量指标。相较于早期版本中使用MeshLab虚拟测角仪插件（Yezzi-Woodley等，2020）计算得到的打击泡角度测量值，本方法与预期的石片破裂面角度协变量（详见Lin等，2025）之间具备更强的统计学关联。同时，该方法对完整石片重量的变异量也具备更强的解释力（详见Li等，2022）。
