R installation and usage for data analysis

Introduction R

Today I provide a brief introduction about recent popular R language.
R is very an effective tool for statistics and graphics.
There are existing statistical programs such as SAS, SPSS.
However R is open source and it has a lot of packages.

The site of R is http://r-project.org.
You can download R program, documents, add-on packages, etc.

If you need to search for R, visit http://rseek.org.

Using R for Big-Data

You should consider something when R is used by Hadoop for big data processing.
R works based on a single core and in memory.
In other words, it is not composed of the distributed environment.

Thus some vendors are using R-Hadoop, R-Hive.

R Installation

Installation of R is very simple.
When you get install file from the R project site, you can install any OS like Mac, Windows, and Linux.

Now you can test R programming.
