Finding and eliminating errors in code is one of (if not the most) frustrating part of computer programming. This week we focus on how to debug and test an R program. We start with the usage of print() statement to analyse the state of function calls and loops. Afterwards, we discuss more structured ways of error-catching and debugging with the help of built-in R debugger.
