calling optimize/fmin from C code
Hi, To make a calculation (an innermost loop) that uses optimize faster, I think I should write things in C. Is it possible to call fmin, which is called by optimize, from C? It is not listed in Writing R extensions, but I found double Brent_fmin(double ax, double bx, double (*f)(double, void *), void *info, double tol); in Applic.h. Is this the function I am looking for? My guess is that ax and bx are the endpoints, f is the function, but what is it's second argument (void *)? What is *info? Or is it some other f...

R.exp file for building packages
I am trying to port some C code from S-Plus (7.0.6) to R (2.4.0) under Windows XP SP2. I use Visual C++ 6.0 to build my library for S-Plus, so I'd like to stick with that set up, if possible. According to the README.packages file, I need the file R.exp (containing functions exported from R.dll, I'm guessing) to build an R package with VC++. >From what I've read in the archives of

R 3.0.0 is released
...odes are now defined using the typedef rcolor. o The REPROTECT macro now checks that the protect index is valid. o Several non-API entry points no longer used by R have been removed, including the Fortran entry points chol, chol2inv, cg, ch and rg, and the C entry points Brent_fmin, fft_factor and fft_work. o If a .External call is registered with a number of arguments (other than -1), the number of arguments passed is checked for each call (as for other foreign function calls). o It is now possible to write custom connection implementations...
