我在Ubuntu机器上的R 3.0.2(2013-09-25)软件包安装过程中遇到此问题:

install.packages("randomForest")
Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
Warning in install.packages :
  'lib = "/usr/local/lib/R/site-library"' is not writable

怎么解决？

我有Ubuntu 16.04,在更新R到3.4.1版之后,即使它们也已更新,它也看不到我的包:

> library(dplyr)
Error in library(dplyr) : there is no package called ‘dplyr’

包裹在那里:

$ ls ~/R/x86_64-pc-linux-gnu-library/3.4/ | grep plyr
dplyr
plyr

我的.libPaths:

> .libPaths()
[1] "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"       "/usr/lib/R/library" 

设置.libPaths到所需的路径只会为一个会话.我希望它是永久性的.

我也尝试设置变量R_LIBS,R_LIBS_SITE并设置R_LIBS_USER到此处所示的所需路径,但它仅在控制台中起作用(在RStudio中不起作用).
