Question

Point out the correct statement?

(a) The traceback() function must be called immediately after an error occurs

(b) The debugger calls the browser at the very low level of the function body

(c) Every time you call the mod() function it will launch the interactive debugger

(d) R provides only two tools to help you with debugging your code

This question was addressed to me in class test.

My question is from Debugging Tools topic in section Control Structures, Functions, Scoping Rules, Loop Functions and Debugging of R Programming

Answer 1

Correct choice is (a) The traceback() function must be called immediately after an error occurs

Easiest explanation: Once another function is called, you lose the traceback.
