r - 天哪，实际上会清除 R 中的 .libPaths 吗？

Question

根据网上的一些答案，我尝试了多种方法：

.libPaths():
[1] "/home/balter/conda/lib/R/library" "/home/balter/R"
> .library=""
> .library.site=c("")
> .libPaths()
[1] "/home/balter/conda/lib/R/library" "/home/balter/R"
> Sys.unsetenv("R_LIBS_SITE");Sys.unsetenv("R_LIBS");Sys.unsetenv("R_LIBS_USER")
> .libPaths()
> .libPaths()
[1] "/home/balter/conda/lib/R/library" "/home/balter/R"
> .libPaths("")
> .libPaths()
[1] "/home/balter/conda/lib/R/library"
> .libPaths("")
> .libPaths()
[1] "/home/balter/conda/lib/R/library"
> .library.site
[1] ""
> assign(".lib.loc", "")
> .libPaths()
[1] "/home/balter/conda/lib/R/library"

我希望能够设置.libPaths为空，或者至少完全是我想要的，没有残差。
