As far as I understood, the original version of Ihaka/Gentleman was written in Scheme. But even if you look at the source version of R 0.49 (the oldest I can find), the source files are written in C. In addition, in their article published in "Journal of Computational and Graphical Statistics" in 1996, Ihaka and Gentleman write on page 307: "To further foster portability, we chose to write R in ANSI C...." Hope this clarifies the situation a bit. If we are lucky and one of the original authors reads this thread they might explain the situation further and better (and probably correct me).
