R on Ubuntu

I have been using R recently. R is statistics programming language. R has attracted more and more attention as analytics in cloud gets more and more hot.

 

Don't install R in default Ubuntu source which only contains a older version. Update apt source according to http://ftp.ctex.org/mirrors/CRAN/. For example, I added the following line to/etc/APT/source. List

 

Deb http://bibs.snu.ac.kr/R/bin/linux/ubuntu jaunty/

 

Follow the instructions from here

1. sudo gedit /etc/apt/sources.list

   This will open up yoursources.listFile ingedit, Where you can add the following line.

2. deb http://cran.cnr.berkeley.edu/bin/linux/ubuntu/ version/

   Replaceversion/With whatever version of ubuntu you are using (eg,precise/,oneric/, And so on). If you're getting a "malformed Line Error", check to see if you have a space/ubuntu/Andversion/.

3. Fetch the secure apt keygpg --keyserver keyserver.ubuntu.com --recv-key E084DAB9Orgpg --hkp://keyserver keyserver.ubuntu.com:80 --recv-key E084DAB9.

4. Feed it to Apt-keygpg -a --export E084DAB9 | sudo apt-key add -

5. Update your sources and upgrade your installationsudo apt-get update && sudo apt-get upgrade.

 

Install R

Sudo apt-Get install R-base-Dev

 

Install rjava

Sudo R cmd javareconf

Sudo R to launch rterm. issue install. Packages ('rjava', dependencies = true) to install rjava.

(Installation of rjava needs root permission so sudo it is needed. sudo R is also needed whenever you want to use rjava in rterm)

Sudo R to launch rtern whenever rjava library needs to be used.

 

There is another way to install rjava. First Run 'sudo chmod-r 777/etc/R'. The do all the operations in the previous text without 'sudo '.

 

Installo other packages

Use sudo R to launch rterm

Install. Packages ('rweka ', dependencies = true)

Install. Packages ('kernlab ', dependencies = true)

Install. Packages ('iswr ', dependencies = true)

 

Install dependencies packages:

 

-Sudo apt-Get install libx11-dev

-Sudo apt-Get install libglu1-mesa-dev

-Sudo apt-Get install libgl1-mesa-dev

 

In R console, run

 

Install. Packages ('rcmdr ', dependencies = true)

 

To install ggplot2 and caret, don't use dependencies = true. Otherwise, a lot of dependent packages

Will be installed. Installation for some of them may fails since some depends on something outside

R (some Ubuntu pacages ).
