[Rcpp-devel] R::nbinom and R::nbinom_mu give identical results?

Dear list, I am trying to call R’s negative binomial function with Rcpp, but encountered some weird behaviour. Here is an example using inline: rcpp_Rf_dnbinom <- rcpp(signature(), ' return wrap(Rf_dnbinom( 4.0, 0.5, 0.9, 1)); ') rcpp_Rf_dnbinom_mu <- rcpp(signature(),

[Rcpp-devel] Initializing Armadillo vec/cube from NumericVector using as conversion

Hi, I was recently hunting down a bug in my code, and stumbled upon a slightly incoherent behaviour in Rcpp/RcppArmadillo. In my real application I have a class which data members are initialized in initialization list from the Rcpp List using as. For example, I have a member y which I initiali

[Rcpp-devel] Rstudio crashes with repeated calls to sourceCpp with Xptr export

Hi, In the bssm package (https://github.com/helske/bssm), I let the users define a state space model via own C++ functions which are then exported as Xptr to R side, and passed back to C++ function for SMC/MCMC etc. Normally this works fine, but when user repeatedly modifies the model function
