Files for brms and MCMCglmm analyses

R documents (.R files) and associated data files used for Bayesian phylogenetic multilevel models. Details are provided as comments throughout R documents. Data files include bird phylogenetic trees (.tre files) and individual specimen and species-level information (.csv files). Resulting model summaries are included (.txt files and brms_model_summaries_100.csv).本数据集包含用于贝叶斯系统发育多层模型（Bayesian phylogenetic multilevel models）的R脚本文件（.R文件）及其配套数据文件。R脚本内的注释已对相关内容进行了详细说明。数据文件涵盖鸟类系统发育树（.tre文件）、个体标本及物种水平信息（.csv文件）。此外还包含生成的模型汇总文件（.txt文件与brms_model_summaries_100.csv）。
