R Setup in Ubuntu

R is a statistical package to analyze data. I came across this framework while exploring Hortonworks Hadoop Data Platform and want to list down the steps to setup R – Steps on how to use R is not covered here:

1. Open Terminal and Run following commands:
~~~
sudo apt-get update
sudo apt-get install r-base
~~~
2. Above would install R 2.14.1. To upgrade to latest version, append following to “/etc/apt/sources.list” and run “sudo apt-get update” once again:
~~~
deb http://cran.rstudio.com/bin/linux/ubuntu precise/
~~~

3. In my Ubuntu, executing above, generated following error:
~~~

W: GPG error: http://cran.rstudio.com precise/ Release: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 51716619E084DAB9
~~~

4. To resolve above error, execute following commands:
~~~
gpg –keyserver pgpkeys.mit.edu –recv-key 51716619E084DAB9
gpg -a –export 51716619E084DAB9 | sudo apt-key add –

5. Run following command to upgrade all packages:
~~~
sudo apt-get upgrade
~~~

Note: To find #packages ubuntu has, use following command – more #packages, more time is taken to upgrade (be ready to do plan for alternative task during this time – upgrade took me 2-3 hours):
~~~
dpkg –get-selections | grep -v deinstall > packages.txt
~~~

6. Run “R” in terminal and we would see R’s console.
