This questions has been discussed in this list about a month ago:
http://r.7896
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
Last time I neeed a 1-d solver, I just quicky coded one up, based on another
implementation of Brent's method. That was a one-off and at work, but it
really isn't that involved.
Otherwise, please do look around at CRAN. There are now 176 packages using
Rcpp, and quite a few use, or implement, op
syntactic sugar equivalent for R's optimize()
function
Hi Rcpp-devel list,
I was wondering if there was a Rcpp equivalent function for R's optimise()
function thats in the stats package?
If not, since Its a single vector optimisation are there some existing
libraries i can use withi
Hi Rcpp-devel list,
I was wondering if there was a Rcpp equivalent function for R’s optimise()
function thats in the stats package?
If not, since Its a single vector optimisation are there some existing
libraries i can use within Rcpp that someone can point me to?
