0.What is the R language

the R language is mainly used for statistical analysis, drawing of the language and operating environment. R was originally developed by Rossihaka and Robertgentleman from the University of Oakland, New Zealand . (also known as R) is now developed by the R Development core team. R is a GNU project based on the S language, so it can also be used as an implementation of the S language , and code written in S can be run without modification in the R environment. The syntax for R is from scheme.

the original code of R can be freely downloaded, and the compiled version of the executable file can be downloaded and run on a variety of platforms, including UNIX ( also including FreeBSD and Linux), Windows and MacOS. R is primarily a command-line operation, while someone has developed several graphical user interfaces.

R built in a variety of statistical and digital analysis functions. the functions of R can also be enhanced through the installation Kit (Packages, user-authored features). Because of the blood of S, R has a stronger object-oriented ( OO programming) function than other programming languages for statistical or mathematical purpose .

Another strength of R is the drawing function, which has the quality of the printing, and the mathematical notation can be added.

While R is primarily used for statistical analysis or development of statistical-related software, it is also used as a matrix calculation. Its analysis speed is comparable to Gnuoctave even business software matlab.
