R Introduction


R is a open source free software programming language for statistical computing and graphics. R was created by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand and is currently developed by the R Development Core Team. R is named partly after the first names of the first two R authors. R software environment is written primarily in C and Fortran. Latest version of R is 3.0.1, code name GOOD SPORT. It takes only 75 – 100 MB of disk space. R is working on three platforms

1. Windows – Require Windows XP or later to install R ver 3.0.1 and it also supports 64 bit machine.

2. Linux – Require Ubuntu i386 and amd64.

3. Mac OS – Require Mac OS X 10.6 (Snow Leopard) and higher.

R provides simple GUI with console.

R GUI

R Studio, latest version 0.97.551 is a powerful GUI for R. It takes only 60 – 100 MB of disk space. I am using R Studio, a superb GUI for R but long way to go to compete with today’s GUI like Websphere, .Net IDE, Oracle and SQL server GUI. It need R engine to run the R code. It has 4 working area under one window i.e. code area, workspace area, console area and file, help, plots and package area. Help is very easy in R. If you know the keyword and want to inquire about its parameter and their usage or example, just use “?” like ?factorial, it will display the help of keyword within the window i.e. lower right corner of screen. If you are not sure about the keyword and use “??” like ??logarithm, it will open all the related keywords in your default browser.

r studio

R Studio Server – To deploy R web application, R studio provides R Studio server ver 0.97.551. It requires Debian version 6 (or higher) or Ubuntu version 10.04 (or higher). RStudio requires a previous installation of R version 2.11.1 or higher.
