推荐答案

install.packages 命令查看 .libPaths 变量.这是我在 OSX 上的默认设置:

The install.packages command looks through the .libPaths variable. Here's what mine defaults to on OSX:

> .libPaths()
[1] "/Library/Frameworks/R.framework/Resources/library"

默认情况下我不在那里安装软件包，我更喜欢将它们安装在我的主目录中.在我的 .Rprofile 中，我有这一行:

I don't install packages there by default, I prefer to have them installed in my home directory. In my .Rprofile, I have this line:

.libPaths( "/Users/tex/lib/R" )

这会将目录/Users/tex/lib/R"添加到 .libPaths 变量的前面.

This adds the directory "/Users/tex/lib/R" to the front of the .libPaths variable.
