Due to the new R 2.11 release, I want to implement Dirk's suggestion here.
由于新的R 2.11版本，我想在这里实现Dirk的建议。
So for that I am asking - How can I (permanently) change R's library path? (The best solution would be one that can be run from within R)
所以我要问 - 我怎样（永久）改变R的库路径？ （最好的解决方案是可以在R内运行的解决方案）

You can edit Rprofile in the base library (in 'C:/Program Files/R.Files/library/base/R' by default) to include code to be run on startup. Append
您可以在基本库中编辑Rprofile（默认情况下在'C：/ Program Files / R.Files / library / base / R'中）以包含要在启动时运行的代码。附加
######## User code ########
.libPaths('C:/my/dir')
to Rprofile using any text editor (like Notepad) to cause R to add 'C:/my/dir' to the list of libraries it knows about.
Rprofile使用任何文本编辑器（如记事本）使R将'C：/ my / dir'添加到它知道的库列表中。
(Notepad can't save to Program Files, so save your edited Rprofile somewhere else and then copy it in using Windows Explorer.)
（记事本无法保存到Program Files，因此请将已编辑的Rprofile保存在其他位置，然后使用Windows资源管理器将其复制。）

I've used this successfully inside R script:
我在R脚本中成功使用了这个：
library("reshape2",lib.loc="/path/to/R-packages/")
useful if for whatever reason libraries are in more than one place.
如果出于任何原因，库在多个地方都很有用。

This post is just to mention an additional option. In case you need to set custom R libs in your Linux shell script you may easily do so by
这篇文章只是提到一个额外的选择。如果您需要在Linux shell脚本中设置自定义R库，您可以轻松地执行此操作

I'm late to the party but I encountered the same thing when I tried to get fancy and move my library and then had files being saved to a folder that was outdated:
我迟到了，但是当我试图想要移动我的库然后将文件保存到过时的文件夹时，我遇到了同样的事情：
.libloc <<- "C:/Program Files/rest_of_your_Library_FileName"
One other point to mention is that for Windows Computers, if you copy the address from Windows Explorer, you have to manually change the '\' to a '/' for the directory to be recognized.
还有一点要提到的是，对于Windows计算机，如果从Windows资源管理器复制地址，则必须手动将“\”更改为要识别的目录的“/”。
