删除所有R不附带的软件包 [英] Remove all packages that do not come with R

问题描述

如何删除除base和recommended之外的所有已安装软件包?

How can I remove all installed packages except base and recommended?

推荐答案

代替

已更新至R 3.0.0，并且必须重建所有软件包.

Updated to R 3.0.0 and have to rebuild all packages.

只是做

update.packages(..., checkBuilt=TRUE)

这是我在R 3.0.0上所做的(使用lib.loc=...指向我的不同本地目录).这将更新您拥有的所有内容，并且仍然可以从存储库中获取，例如CRAN.对于install_git()等，您不走运，需要重新安装.

which is what I did on my R 3.0.0 (using lib.loc=... to point to my different local directories). This will update everything you have and which it can still get from repos such as CRAN. For install_git() etc, you are out of luck and need to reinstall.

但是，无论哪种方式， 都不需要先删除软件包.

But either way you do not need to remove the packages first.
