The task of collecting the source program is entrusted to a separate program called pre-processor. In R, withCallingHandlers() is a variant of tryCatch(). From the perspective of using JIT with R, the above means that the {compiler} package does not offer a jit compiler to a machine code, but it does offer it in order to turn it into byte code. Another way to activate browser() is to use options(error = recover). In either case, work on making the smallest possible reproducible example (Section 1.7) to help the developer help you.
