I just updated to R (3.4.1 \"Single Candle\") on my Linux Mint 18.1 Cinnamon machine and I attempted to install a package. R returned the following:
> ins
My solution was the following:
In the file /usr/lib/R/etc/Renviron there is a configuration of R.
In lines 43-45 there is:
# edd Jun 2017 Comment-out R_LIBS_USER
#R_LIBS_USER=${R_LIBS_USER-'~/R/x86_64-pc-linux-gnu-library/3.4'}
##R_LIBS_USER=${R_LIBS_USER-'~/Library/R/3.4/library'}
I have uncommented R_LIBS_USER=${R_LIBS_USER-'~/R/x86_64-pc-linux-gnu-library/3.4'}, restarted RStudio and now it works.
EDIT: Looking at the comments, it seems like a planned behaviour. Here is another solution.
