<p class=MsoNormal>Hello all.<o:p></o:p></p>

I installed and looked at RcppExamples, but (at least from its documentation)
most of these refer to RcppClassic?. Besides that, I did some googling but that

suggestions to Mr. Eddelbuettel and other Rcpp authors (I expect some of them
to read this): the class hierarchies and the like, provided by doxygen, are
really neat when you are already kneedeep into Rcpp, but for a beginner (in
Rcpp), I am more interested in a list of 'this method in this class does this
like that function in R' rather than 'you can find the declaration of this
operator in this header file'. After all, I understand one of the goals of Rcpp
is to lower the threshold for using C++ in R? Note: from what I have seen and
understood, I highly value the actual code of Rcpp and have the highest respect
for its creators. If the lack of basic documentation is merely a result of
'lack of resources', I would be willing to become a resource (e.g.: work on
'basic' documentation once I get through it myself).<o:p></o:p></span></p>
