R supports several powerful features, such as first-class functions, functions on the left-hand side of an assignment, and explicit environment objects that bind variables to values. Taken together, these make R a powerful language for functional programming. This course will show you how to work effectively with functions in R. Specifically, you'll learn how to create and invoke functions in R and leverage R support for functional programming and first-class functions. You'll recognize how an R environment is a virtual binding between variable names and values. You'll create nested environments and leverage the fact that individual functions have their own local environments. You'll also create and invoke closures as well as replacement functions. By the end of the course, you'll have the confidence to work with functions in your R programming projects.
WHAT YOU WILL LEARN
-
discover the key concepts covered in this course
recall how built-in functions can be viewed and new functions created
introduce the return function and recall ways of returning data without invoking it
implement the use of named arguments to pass in data to functions
specify default arguments for functions
specify functions as input arguments to other functions
use functions with switch statements and store functions in other data structures -
recall the use of R environments as bindings of variable names to values
create inner nested functions within outer functions
recognize the nested environments created by default within a function
implement closures, which include the environment, body, and input arguments to a function
create and use replacement functions to specify functions that can be l-values
