interception of expression evaluation. What is the right way to proceed?
I am a computer science lecturer at IST (www.tecnico.ulisboa.pt) andhave
been developing a voluntary computing environment for R together with
some students. The idea is to allow R users to share their CPU time in
the community. Both for security of the volunteers (to create a sandbox)
and for debugging support, we have extended the R interpreter with a
small intervention in the eval function.
My question is the following:
- Is there any way to transparently intercept all expressions in the R
runtime? and in a way we should not have touched the internals of the
- If changing the interpreter is the way to go, what is the correct way
to propose this change to the R community?
