The R Programming Language Ris a programming language built on functions. A function is a collection of statements that carry out a task. In R, almost every statement you write is a function, fromc(create a vector) toprint. Even adding two numbers calls a function!
R is a powerful programming language that comes with a wide catalog of built-in functions that can be called anytime. As a math-oriented language, R comes with a good number of functions to perform numeric operations. Below you can find a list of some of the most useful: print(). Disp...

The R programming language on its own is a powerful tool that can perform thousands of statistical tasks, but by writing programs in R, you gain tremendous power and flexibility to extend its base functionality. Senior Succinctly® series author and editor James McCaffrey shows you how in R ...
★Generally in R, functional programming is much more important than object-oriented programming, because you typically solve complex problems by decomposing them into simple functions, not simple objects. ” 相比起面向对象编程,对于R 的使用者来说,通常我们更加广泛运用的是函数式编程——通过将大问题拆解...
The return value is the last stage of any function. In this particular phase, this statement tells about the value that is being returned to the place where the function is called. In the R language, there are numerousbuilt-in functions. Thus, these can be directly used without defining at...
However, in R you can have functionsdefined inside other functions -Languages like C don’t let you do this Now things get interesting — In this casethe environment in which a function is defined is the body of another function! make.power<- function(n) { ...
constructors exist for types and one type can inherit from another type. The difference is that types do not have embedded methods. In functional programming, functions are first class so there is no need to embed them within the data structure. Using types provides type safety, which means ...
