Just like most programming languages, R supports coding characteristics that you could use to regulate the move of plan execution, determine functions which can conduct distinct tasks, perform with common data styles, like strings and dates, and make your code a lot more robust by intercepting most likely problems and dealing with them ahead of they interrupt the execution of one's code. In this module, you’ll learn how to implement these elementary programming duties in R.
