我的问题是如何确定列表中的哪个文件与我的R版本兼容?

My question is how do I determine which file there in the list is compatible with my R version?

推荐答案

您可以使用 METACRAN镜像:

转到您感兴趣的程序包的DESCRIPTION文件的 blame 页面.

Go to the blame page of the DESCRIPTION file of the package you're interested in.

例如对于tm: https://github.com/cran/tm/blame/master/描述

找到Depends行，并根据需要在查看此更改之前的视图责备图标上单击所需的次数，直到显示足够旧的R版本.

Find the Depends line and click as many times as needed on the View blame prior to this change icon, until an old enough R version is displayed.

如果您想自动化，最好使用 crandb (同样来自METACRAN).

If you want to automate that, it may be better to use crandb (also from METACRAN).

旁注:有时程序包作者将R (≥ x.y.z)列为依赖项只是为了安全起见，因为他们使用版本x.y.z并且未对先前版本进行任何测试.

Side note: sometimes package authors list R (≥ x.y.z) as a dependency just to be safe because they use version x.y.z and didn't do any tests with previous versions.
