From RcppArmadillo I can see, that the registerPlugin function is never called inside the package - but I see also, that the file is called inline.R. How does the inline package register/identify a plugin? Is a plugin registered automatically when called inside cxxfunction? Does it have to be put into a file called 'inline.R'?

plugin callbacks...) but when a plugin is invoked, it points to a package and
hence the package namespace is searched and a corresponding function is
