Thanks a lot, Baptiste!
I'll check your code asap.

Hi,
I might be the author of the SO question you refer to. In the planar
package I've tried a number of different strategies for numerical
integration, but the most efficient I managed was at the C++ level, with
direct call to the cubature library,

Dear Dirk, thanks for your answer, I'll keep studying and decide what way
to follow.
Dear Qiang, here's the code for the function (I already did some work to
the math behind the density itself in order to quicken a bit)
library(cubature)
library(zipfR)
dcbinom <- Vectorize(function(x,nu,pp) { #
Hi,
The backend of cubature package is the cubature C library from MIT. The
same author with nlopt.
Can you give a little more detail about the double integral? Cubature
should not be that slow from my experience.
Best,

Dear all,
I was wondering what, in your opinion, would be the best way to handle the
computation of definite integrals using Rcpp.
To be more precise, I need to evaluate a double integral that turns out to
be somewhat nasty (really slow computation and presumably inaccurate
results using the R cu
