I think the safest bet would be to handle dispatch at the R level, which
would then call your internal C++ implementations. At least, it would be
easier / cleaner. Otherwise, you're right, you need to perform an 'ad-hoc'
dispatch based on the internal type / class and such.

Thanks, Dirk!
Follow up: That also means (I guess) that to be on the safe side I should write
a check-function that will check that the INTSXP and REALSXP really is a
matrix, i.e. that it has a dim attribute; right? Or are there facilities for
that?

Dear all,
I want to do some computation on a matrix, irrespective of whether it is a
numeric matrix, an integer matrix or a sparse matrix (a dgCMatrix which can be
handled with RcppEigen). For simplicity, I want to compute the sum of the
elements.
To do so I use a template

Is this really the important thing? Seems like -g0 saves disk space, not memory?
(Loading the symbols into a debugger may require lots of memory, but that
is not the issue here.)
Header-only C++ packages require the compiler to effectively process one
