It is the latter that is generally recommended. There are different packages that help with writing and running tests in R such as RUnit and testthat. In the case a bug is discovered with a function, a test should always be written to ensure that bug is not reintroduced at some point in the future - you are essentially protecting yourself from future you’s mistakes. In fact, some people use a test driven development approach whereby tests are written first and a function is written second to pass those tests. It also means that we can build tests to ensure the code continues to work as expected when we make changes to it.Įverytime you write a new function, you should strive to write tests for that function. Writing functions allows us to more easily document our code meaning that others can use it without too much hassle. In functional programming, code is designed to be reused again and again with different inputs, making for simpler code that is easier to understand and audit. Advice includes functions and syntax to avoid, package structure, code complexity, code formatting (using lintr) and more. The goodpractice is useful for giving advice about good practices when building R packages. Note that not all aspects of this may match the guidance we have provided above but it can at least begin to help you to refactor your code to be more accessible.
