Using a small Java tool that drives the gcc preprocessor and runs some specialized regex queries yields the following reports on actual usage of the macros, typedefs, variables and functions defined in various R header files.
The usage counts were determine by scanning all CRAN source files (the CRAN dump is from mid-March 2016). They may include false positives because this was done on a textual base only. The packages "SOD" and "Boom" were ignored because they contain many false positives.
- Native API stats of R.h
- Native API stats of Rinternals.h without USE_R_INTERNALS
- Native API stats of Rinternals.h with USE_R_INTERNALS
- Native API stats of all header files
