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
sudo gedit /etc/apt/sources.list
This will open up your sources.list file in gedit, where you can add the following line.
deb http://cran.cnr.berkeley.edu/bin/linux/ubuntu/ version/
Replace version/ 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 between /ubuntu/and version/.
Fetch the secure APT key with gpg --keyserver keyserver.ubuntu.com --recv-key E084DAB9 or gpg --hkp://keyserver keyserver.ubuntu.com:80 --recv-key E084DAB9.
Feed it to apt-key with gpg -a --export E084DAB9 | sudo apt-key add -
Update your sources and upgrade your installation with sudo 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 of
R (some ubuntu pacages).
