Hi all,
I am just starting using Rcpp to accelerate some computations. I need to
evaluate some likelihood using common math functions like beta, lbeta,
gamma, lgamma, choose, lchoose, etc. But I found that it could be even
slower in Rcpp than R? Please see the example below using Rcpp..

Hi all,
I am calling from R (say funcR) a c++ function (say funcCpp) which needs
either some programmer-defined c++ class (say programmerClassCpp1, 2,
etc...) or a user-defined c++ class (say userClassCpp). Here is an
illustration of what I am doing:
funcR(..., class="ClassCpp"){
# do somethin
Apologies if this is a naive question - I'm a beginner with Rcpp. I did see
some earlier discussion on similar topic, but I don't think it answered my
questions.
I am trying (on Windows) to speed up a function currently written in R. This
works very well for real-valued arguments of the funct
Hi,
I think you can/should use std::complex, see for example the types used in

In general I prefer to work with RcppArmadillo for numerical (including
complex) computations, its syntax closely follows R and Matlab. See for
