R code

The sample R code provides an example of the models used. They are Monte Carlo Markov-chain models, fit with the R package MCMCglmm. One model uses a phylogenetic tree to estimate relatedness and the other uses nested taxa. Each model uses one of these measures of relatedness as a random effect to control for phylogeny. More information about using this code can be found in the documentation for MCMCglmm.

本示例R代码给出了所用模型的实现范例。这些模型均为马尔可夫链蒙特卡洛（Markov Chain Monte Carlo, MCMC）模型，通过R软件包MCMCglmm进行拟合。其中一款模型借助系统发育树估算亲缘关系，另一款则基于嵌套分类单元开展亲缘关系估算。两款模型均以其中一种亲缘关系度量指标作为随机效应，以控制系统发育带来的混杂影响。有关该代码的更多使用说明，可查阅MCMCglmm的官方文档。
