R升级到3.4安装包

Question

在我决定升级到 3.4 之前，我的 R 一直运行良好。现在我无法安装软件包。

安装包时出现错误

Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
Warning in install.packages("ggplot2") :
  'lib = "/usr/local/lib/R/site-library"' is not writable
Would you like to use a personal library instead?  (y/n) 

如果我点击是，我得到

Would you like to create a personal library
NA
to install packages into?  (y/n) 

在哪一点它继续给出这个错误

Error in install.packages("quantstrat") : unable to create ‘NA’

Answer 1

我不知道为什么R 3.4.1 改变库路径。要改回来，只需编辑 /etc/R/Renviron:

$ sudo gedit /etc/R/Renviron

注释掉 R_LIBS_SITE=... 然后取消注释 R_LIBS_USER=...

# edd Jun 2017  Comment-out R_LIBS_USER
R_LIBS_USER=${R_LIBS_USER-'~/R/x86_64-pc-linux-gnu-library/3.4'}

# edd Apr 2003  Allow local install in /usr/local, also add a directory for
#               Debian packaged CRAN packages, and finally the default dir 
# edd Jul 2007  Now use R_LIBS_SITE, not R_LIBS
#R_LIBS_SITE=${R_LIBS_SITE-'/usr/local/lib/R/site-library:/usr/lib/R/site-library:/usr/lib/R/library'}
