Problem with Project R installation

Question

I don't know where to put this line in the file. Or is there the possibility to achieve it over the shell somehow? I'm using 14.04.

INSTALLATION

To obtain the latest R packages, add an entry like

deb http://<my.favorite.cran.mirror>/bin/linux/ubuntu trusty/ or

deb http://<my.favorite.cran.mirror>/bin/linux/ubuntu precise/ or

deb http://<my.favorite.cran.mirror>/bin/linux/ubuntu lucid/

in your /etc/apt/sources.list file, replacing <my.favorite.cran.mirror> by the actual URL of your favorite CRAN mirror. See http://cran.r-project.org/mirrors.html for the list of CRAN mirrors. To install the complete R system, use

sudo apt-get update
sudo apt-get install r-base

My mirror would be: http://stat.ethz.ch/CRAN/

Answer 1

Add the following line to your /etc/apt/sources.list file. It doesn't matter where exactly, but end of the file is ok.

deb http://stat.ethz.ch/CRAN/bin/linux/ubuntu trusty/ #enabled-manually

If you insist on doing this in a terminal, do the following:

sudo su 
echo "deb http://stat.ethz.ch/CRAN/bin/linux/ubuntu trusty/ #enabled-manually" >> /etc/apt/sources.list
exit

This will launch a super user session, and append the line to the sources.list file, after which we exit from the super user session.

Then, per the R installation instructions, one must add the public key of Michael Rutter to secure apt. Execute the following in a terminal:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9

Then simply do sudo apt-get update && sudo apt-get install r-base r-base-dev.

Happy R-ing!
