Hi Christian,
Thanks for catching this. I think this is an oversight -- this should
return `R_len_t` as well. Or, when long vector support is implemented,
`R_xlen_t` should be used instead (especially since `ListOf` is
more-or-less a fancy interface over a `List` object)
Just pushed a correspondi
Minor implementation question -
As a learning exercise, I'm working through g++ warnings. After
reading SO posts r.e. int vs size_t, I've set all variables that hold
or compare object size information to type std::size_t. This fixes
compiler warnings for Vector.size(), which doxygen shows have re

Hmm already spotted a typo. That second block should of course have starte

Greg, would you be interested in writing up a simple Rcpp Gallery post
on that?
I would be happy to help if you'd prefer that.
Many thanks for the invitatio

These days you need only one Import: statement to instantiate Rcpp.
