In base R, there are lots of environment variables with either prefix 'R_' or '_R_', e.g. R_ENABLE_JIT and _R_RNG_VERSION_. I always considered R_* variables to be "public" and _R_*_ ones being "internal" but realized I don't have a reference for this. Is this true, or is there another reason? Is the difference between the two kinds documented anywhere?
