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'? 

What is your actual intent?  To support inline? To support Rcpp Attributes?

I have not looked at this in a while, but I think we may not actually
required registration (ie there is no run-time state vector accumulating
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
called.

This is from memory. Actual details may differ. Void where prohibited :)
