如何在R中重置或完全覆盖.libPaths？
如何在R中重置或完全覆盖.libPaths？

我想让.libPaths()返回"/home/balter/R" "/home/balter/conda/envs/dada2/lib/R/library"。
这就是我所得到的：
> .libPaths()
[1] "/home/balter/R" "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"
[4] "/usr/lib/R/library"
> .libPaths(new='/home/balter/conda/envs/dada2/lib/R/library')
> .libPaths()
[1] "/home/balter/conda/envs/dada2/lib/R/library" "/usr/local/lib/R/site-library"
[3] "/usr/lib/R/site-library" "/usr/lib/R/library"
> .libPaths(new=c("/home/conda/envs/dada2/lib/R/library", "/home/balter/R"))
> .libPaths()
[1] "/home/balter/R" "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"
[4] "/usr/lib/R/library"
> .libPaths(c("/home/conda/envs/dada2/lib/R/library", "/home/balter/R"))
> .libPaths()
[1] "/home/balter/R" "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"
[4] "/usr/lib/R/library"
> .libPaths(c("/home/conda/envs/dada2/lib/R/library", "/home/balter/R"))
> .libPaths()
[1] "/home/balter/R" "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"
[4] "/usr/lib/R/library"
> .libPaths(new=c("/home/conda/envs/dada2/lib/R/library", "/home/balter/R"))
> .libPaths()
[1] "/home/balter/R" "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"
[4] "/usr/lib/R/library"
> .libPaths(new="home/balter/R")
> .libPaths()
[1] "/usr/local/lib/R/site-library" "/usr/lib/R/site-library" "/usr/lib/R/library"
> .libPaths("home/balter/R")
> .libPaths()
[1] "/usr/local/lib/R/site-library" "/usr/lib/R/site-library" "/usr/lib/R/library" 我似乎不能清理和重置路径。
注意：
这是在本地主机上的WSL Ubuntu18.04中运行的RStudio服务器免费版本。
注二：
@Dason指出了一个打字错误。纠正它我有：
> .libPaths()
[1] "/home/balter/R/x86_64-pc-linux-gnu-library/3.4" "/usr/local/lib/R/site-library"
[3] "/usr/lib/R/site-library" "/usr/lib/R/library"
> .libPaths(c("/home/balter/conda/envs/dada2/lib/R/library", "~/R"))
> .libPaths()
[1] "/home/balter/conda/envs/dada2/lib/R/library" "/home/balter/R"
[3] "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"
[5] "/usr/lib/R/library"
