Rstudio修改默认library安装位置

主要是在清理Linux的home目录，之前使用 Rstudio 一直会在home目录下建立一个安装library的文件，功能也很单一。但是一直也没找到什么好的修改方法。

今天晚上查阅了下，修改成功，特此记录。

其实很简单R的libPaths()命令记录了安装library的位置，但是具体这个信息记录在何处呢？

查找下在/usr/lib/R/etc/下的Renviron文件中。找到这一行


R_LIBS_SITE=${R_LIBS_SITE-'/home/XXX/Archive/software/R/x86_64-pc-linux-gnu-library/3.0/:/usr/local/lib/R/site-library:/usr/lib/R/site-library:/usr/lib/R/library'}

当然上面包含XXX的路径修改成你希望的存储目录即可。

修改之后的再次在R中运行libPaths()命令的结果是:

> .libPaths()
[1] "/home/XXX/Archive/software/R/x86_64-pc-linux-gnu-library/3.0"
[2] "/usr/local/lib/R/site-library"                                  
[3] "/usr/lib/R/site-library"                                        
[4] "/usr/lib/R/library"
