R Programming

R is a scripting language for data analysis. It is both flexible and powerful that gains the supports from many data miners and statisticians. With the large set of statistical and graphical functions, results from the statistical analysis can be displayed either on the screen or export for subsequent analyses. Graphics can be exported to various file formats for presentation. The fast growing and high demand of R in the data analysis fields can explain why it is consistently highly ranked on the most wanted programming language.
