How do you write a function in R?
Writing Functions in R. All of the work in R is done by functions, down to the lowest level. For example, there’s a function named “+” that does addition. There are perhaps 2000 or so functions built in to R, many of which never get called by the user directly but serve to help out other functions.
What does if function mean?

What are the functions of R?
In R, a function is an object so the R interpreter is able to pass control to the function, along with arguments that may be necessary for the function to accomplish the actions. The function in turn performs its task and returns control to the interpreter as well as any result which may be stored in other objects.
What is anonymous function in R?
Anonymous functions. In R, functions are objects in their own right. They aren’t automatically bound to a name. Unlike many languages (e.g., C, C++, Python, and Ruby), R doesn’t have a special syntax for creating a named function: when you create a function, you use the regular assignment operator to give it a name.
