The history of life unfolds within a   phylogenetic context. Comparative phylogenetic methods are statistical   approaches for analyzing historical patterns along phylogenetic trees. This   task view describes R packages that implement a variety of different comparative   phylogenetic methods. This is an active research area and much of the   information is subject to change. One thing to note is that many important   packages are not on CRAN: either they were formerly on CRAN and were later   archived (for example, if they failed to incorporate necessary changes as R   is updated) or they are developed elsewhere and have not been put on CRAN   yet. Such packages may be found on GitHub, R-Forge, or authors' websites.

生命史是在系统发育的背景下展开的。比较系统发育方法是分析沿着系统发育树的历史模式的统计方法。这个任务视图描述了实现各种不同的比较系统发育方法的R包。这是一个活跃的研究领域，许多信息可能会发生变化。需要注意的一点是，许多重要的软件包不在CRAN上：要么它们以前在CRAN上，后来被归档（例如，如果在更新R时它们没有包含必要的更改），要么它们是在别处开发的，并且还没有放到CRAN上。这些软件包可以在Github、R-Forge或作者的网站上找到。
