Brief introduction

R (http://www.r-project.org) system) is a computer language and analysis tool for statistical analysis and graphics. In order to ensure the performance, its core calculation module is written in C, C++ and Fortran. At the same time, for ease of use, it provides a scripting language, namely R language. R language is similar to S language developed by Bell Labs. R supports a series of analytical techniques, including statistical testing, predictive modeling, data visualization and so on. Many open source extension packs can be found on CRAN (http://cran.r-project.org)).

The preferred interface of R software is the command line interface, which invokes the analysis function by writing scripts. If you lack programming skills, you can also use a graphical interface, such as RCommander (http://socserv.mcmaster.ca/jfox/Misc/Rcmdr/) or Rattle (http://rattle.togaware.com)). [2]

In addition, because R system is the focus of this paper, it will spend a lot of space on its various characteristics, advantages and disadvantages.

Main function
