R: a Programming Language

It is certain that R is a widely used statistical computing programming language. And it is promising for any other programming area. It is hard to change routines of programmers. That's why, many questions arise when a new thing comes up in the field, like;

• Do I need to learn R?
• Tell me what i can not do with other languages that i can do with R.
• Why choose R?
• Isn't it a statistical tool, why do i need to use it?
• ...

There are many reasons to choose R. In this post i want to change the resistance of habits to choose R in some areas that you work on.
