Code chunk options that would normally go ```{r HERE} can also be used: just start the line with #+ (instead of #'), and then specify your options, separated by commas. Error Handling is a process in which we deal with unwanted or anomalous errors which may cause abnormal termination of the program during its execution. XCODE key will compile an encrypted source code with key as key. Now when you get an error, youll get an interactive prompt that displays the traceback and gives you the ability to interactively debug inside any of the frames: You can return to default error handling with options(error = NULL). ), When you cant explore interactively, its particularly important to spend some time making the problem as small as possible so you can iterate quickly. . hence interpreter is less efficient than compiler. Ignore these: they are .rs.restartR() if in RStudio); (Quit and restart a clean R session from within R?). How do I fix this?

I struggled with this all day and into the night trying every permutation I could think of and finally found this solution - hopefully this will save someone from going through this nightmare. One drawback to traceback() is that it always linearises the call tree, which can be confusing if there is much lazy evaluation involved (Section 7.5.2). Smarter applications are making better use of the insights gleaned from data, having an impact on every industry and research discipline.

Unfortunately thats beyond the scope of this book, but there are a few resources that you might find useful: Debugging is most challenging when you cant run code interactively, typically because its part of some pipeline run automatically (possibly on another computer), or because the error doesnt occur when you run same code interactively.
