/*
|
|
* note : RcppExport is an alias to `extern "C"` defined by Rcpp.
|
|
*
|
|
* It gives C calling convention to the rcpp_hello_world function so that
|
|
* it can be called from .Call in R. Otherwise, the C++ compiler mangles the
|
|
* name of the function and .Call cannot find it.
|
|
*
|
|
* It is only useful to use RcppExport when the function is intended to be called
|
|
* by .Call. See the thread http://thread.gmane.org/gmane.comp.lang.r.rcpp/649/focus=672
|
|
* on Rcpp-devel for a misuse of RcppExport
