R data statistical analysis software is an excellent statistical software existing for Linux. Right now there is an installing package for Windows too. In addition to this, it gives us a friendly graphic user interface. It is simple and powerful and free to use. So, compared with the popular statistical software such as SPSS, SAS, it has more obvious economical advantages.
