The only difference is tryCatch() deals with exiting handlers while withCallingHandlers() deals with local handlers. Otherwise, you can insert a call to browser() where you want to pause, and re-run the function. There are basically three methods to handle such conditions and errors in R : Unlike other programming languages such as Java, C++, and so on, the try-catch-finally statements are used as a function in R.
