**Abstract**

The fact that R is a language may deter some users who think “I can`t program". This should not be the case for two reasons. First R is an interpreted language, not a compiled one meaning that all commands typed on the keyboard are directly executed without requiring tobuild a complete program like in most computer languages (C, FORTRAN, Pascal . . .). R`s syntax is very simple and intuitive For instance a line a regression can be done with the command lm(y ~ x) which means “fitting a linear model with y as response and x as predictor". In R in order to be executed a function always needs to be written with parentheses even if there is nothing within them (e.g., ls()).R can be considered as a different implementation of S and is much used in as an educational language and research tool. The main advantages of R are the fact that R is freeware and that there is a lot of help available online. It is quite similar to other programming packages such as Mat Lab, but more user-friendly than programming languages such as C++ or FORTRAN and python etc.
