[R-pkg-devel] How ton print in the console from Rcpp

[Elysée Aristide]

Greetings,

I would like to follow up on this issue.
First of all, thank you to everyone who took the time to think about the issue.
As Mr. Dirk Eddelbuettel suggested,  I investigated other packages that perform numerical optimizations using RcppNumerical. The only difference I saw is that all those packages put

#define NDEBUG

after #include <RcppArmadillo.h>.
I did the same thing without understanding :). This solves the issue.


Best,
Aristide

This is the only way I know to compute integrals of perform numerical optimizations in Rcpp. The other way might be: construct the function to be minimized in Rcpp and use the function optim in R. But this is not efficient.

That package is also used by others [1] and you should maybe study their code
and setup as it seems unlikely to me that your woes are due to
RcppNumerical. It likely is a simple inadvertent issue in your package.

[1] https://cloud.r-project.org/web/packages/RcppNumerical/index.html shows
Reverse imports:
  BayesPPD, ccdf, glmdisc, MCPModPack, secr, teachingApps
Reverse linking to:
  apeglm, BayesPPD, BVSNLP, CDatanet, COMIX, fido, gbeta, glmdisc,
  MCPModPack, OwenQ, secr, teachingApps, vennLasso, ztpln
which should give you plenty of examples.
