Umm, you know,

1. there is some reason why not everything is exported from libR.so, 
particularly those parts of the API that are matter to change or are 
undocumented for other reasons.

2. if you do not want to listen to 1.:
R is open source, hence no need to reverse-engineer or "hack" anything 
there, just change the sources and recompile in a way that they export 
those names.

Best,
