Thank you, Chris and Duncan. It never occurred to me to look in optimize.c since optimize() does univariate minimization. Furthermore, now I know that the underlying Fortran code (OPTIF9) is from the UNCMIN library (may be this should be mentioned in the help page, although once can get to this information from the second reference).

I don't see why you say it's not useful, because it's the starting point to find the code. See Ligges, U. (2006): R Help Desk: Accessing the Sources. R News 6 (4), 43-45. http://cran.r-project.org/doc/Rnews/ for the next steps. (To save you some time: look in src/main/optimize.c. But Uwe's article would have got you there pretty quickly).
