R中有标准库这样的东西吗？

Question

几乎每一种主要的编程语言都带有一个标准库。好像R没有。 CRAN 上有大量自定义包，但我找不到符合 "standard library" 条件的东西。 base 包似乎很接近，但是还有 recommended 包，我无法达成共识，哪个最接近所谓的 "standard library".

Bill Dunlap 分享了有关如何识别您的 R 版本标准发行版附带的所有软件包的代码。

i <- installed.packages() 
i[ i[,"Priority"] %in% c("base","recommended"), c("Package", "Priority")]

"recommended" 包随 R 一起提供，但不会在 R 启动时加载。

编辑以包含来自 joran 的评论："Those packages are recommended, and will be in binary installations, but maybe not source installations of R."

Is there such a thing as a standard library in R?
