Out of the box, Revolution R v7.0 works perfectly when step-by-step debugging.
However, executing this line will prevent step-by-step debugging from working:
options(error=recover)
The solution is to set error recovery back its defaults, then step-by-step debugging will start to work perfectly again:
options(error=NULL)
To reproduce this error, create a ReferenceClass in R with an initialize method, set options(error=recover), then attempt to debug into the initialize method.
You will get the error "Unable to step. The method or operation is not implemented." if you have a breakpoint inside the initialize method:
You will get this error if you attempt to step over the initialize method:
