I hope I am not telling you what you already know. There are working examples of "C Standalone" programs that link with R mathlib. I learned from the examples here http://www.math.ncu.edu.tw/~chenwc/R_note/index.php?item=standalone and http://www.stat.berkeley.edu/classes/s243/rmath.html I can't say for sure if these give you access to all of the R stuff you want, but you do get access to quite a bit.
