Rcpp Rcpp.package.skeleton(“mypackage”) “rcpp_hello_world” not available for .Call() for package “mypackage”

Question

I\'ve managed to get the Rcpp.package.skeleton to INSTALL in Windows by the following commands at the R prompt -

Rcpp.package.skeleton(\"mypackage\"         


        

Answer 1

If the package NAMESPACE file contains the line useDynLib(mypackage, .registration = TRUE) (perhaps via a roxygen line #' @useDynLib, .registration = TRUE), then it is necessary to remove PACKAGE = "mypackage" from .C / .Call function calls:

i.e. .Call( "rcpp_hello_world", PACKAGE = "mypackage") becomes .Call("rccp_hello_world").
