We often come across errors while coding. In R, when a function returns an error, there is an easy way to figure out which command have triggered the error. All we need is to use the traceback function.

This helps a developer to find out where and why the error occured. Once the error is traced it is easy for debugging and rectifying the error. The function syntax is as follows,


The traceback() by default prints the call stack of the last error. Apart from tracing the errors, this function is also helpful in times if we require to print the current stack.

Note: The errors caught via try or tryCatch will not generate a traceback
