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++.

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...
