How to install R version 3 [closed]

问题:

After having some problems to install new version of R from command line on Ubuntu (straightforward way just updated it to version 2.15.x)

I want to share the way to do this.

回答1:

This is an old post and I wrote it when it was impossible to install R with simple (it was installing old 2.15 version):

sudo apt-get install r-base-core

Right now you do not need to do all written below and can simply use the abovementioned command. At the time of updating it will give you 3.1 version.

Here is previous post

Uninstall old R

sudo apt-get remove r-base-core

Open sources.list

sudo nano /etc/apt/sources.list    

and add deb to it

deb http://cran.rstudio.com/bin/linux/ubuntu precise/

precise is your ubuntu name (may be different)

Add key to sign CRAN packages

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

Add specific PPA to the system

sudo add-apt-repository ppa:marutter/rdev
sudo apt-get update
sudo apt-get upgrade

installing

sudo apt-get install r-base

From R to check version

version

should give you

version.string R version 3.0.0 (2013-04-03)

Hope people will find this helpful
