a) R is not C.

b) No, we don't have an R compiler (except - in development - a byte 
compiler written by Luke Tierney, but that won't save magnitudes).

You might want either to optimize the code, given it not very well 
written, or reqrite parts of the code in C. See the "Writing R 
Extensions" manual.
