R-script (code) to Fig. 1A-B and Table A1

This file contains the R-script and code that can be used to generate Fig. 1A-B and Table A1 in the manuscript. These figures show geographic variation in species frequencies (Fig. 1A) and density-differences between population categories (Fig. 1B), as well as the statistical tests (ANOVA and GLM) for comparison of these categories. Data-file associated with this script is provided separately.

本文件包含可用于复现论文中图1A至1B以及表A1的R脚本（R-script）代码。上述图表分别展示了物种频率的地理分布差异（图1A）、不同种群类群间的密度差异（图1B），同时附带用于对比这些类群的统计检验方法：方差分析（ANOVA）与广义线性模型（GLM）。本脚本配套的数据文件将另行提供。
