wrapr: 'wrapr': Wrap R Functions for Debugging and Parametric...

Description Details

Description

Provides DebugFnW() to capture function context on error for debugging, and let() which converts non-standard evaluation interfaces to parametric standard evaluation interfaces. DebugFnW() captures the calling function and arguments prior to the call causing the exception, while the classic options(error=dump.frames) form captures at the moment of the exception itself (thus function arguments may not be at their starting values). let() rebinds (possibly unbound) names to names.
