I have just noticed that optimize() is already a C function, as is suggested
below:
> stats::optimize
function (f, interval, ..., lower = min(interval), upper = max(interval),
maximum = FALSE, tol = .Machine$double.eps^0.25)
{
if (maximum) {
val <- .External2(C_do_fmin, function

"In short, this is not trivial."
No, it isn't. If you are not completely wedded to optimize(), I would suggest
another route. Again, I recommend nlopt or some other package which has the
algorithms you need. And you can investigate nloptr if you want to call the
routines in that R package as Di
Hello,
I developed a Rcpp module which compiles and works fine on linux and
win32 but fails to compile on win64.
This module makes a "call lib" to a dll compiled with visual and the "R
CMD INSTALL" fails during the link process with a message

Hi Thell,
Thanks for all the work you've done investigating this. Can you please
consolidate the information you have and post it as an issue here:

And, if you're willing to dive in and figure out what exactly is
happening, patches are much appr
Hi All,
it seems that this is currently not supported.
For this:

double levelDistance=50, double treeDistance=50,
bool orthogonalLayout=false,
