Dear Dirk,
Thanks for your detailed comments!
Regarding the first question: as I wrote, I was actually assuming that
Rcpp would not make deep copies.
[...]
See this variant:
R> fun<- cxxfunction(signature(mat="numeric"), plugin="Rcpp", body='
+ Rcpp::NumericMatrix matC(mat);
+ Rcp
There are in total four slides, and the 2nd is my favorite.
I guess one needs to learn more to like the advanced parts.

Hi Dirk,
Yes. I can already feel its power. How much one can make out of it really
depends on how much s/he is willing to learn. And I am so glad there is a
nice list where we can ask questions.

Pleasure -- it was clear that you done some careful reading to find this.
Keep plugging along, check als
A fair question (although on R itself) and a reference to slides I am
glad I have now seen.
An even better reply by Dirk.

Hi Ulrich,
These are really several questions. I'll try to address them all, with some
luck maybe Romain, Doug, Christian, ... will correct or complement as needed.

Hi!
I recently learned how to deal with overlaoded functions when I wanna wrap a
class function interface with overladed things. The solution is to use function
pointers. Now, what comes to the rescue in the case of overladed constructors?
Any suggestion?

Dear list members,
I have started developing a package using the latest version of Rcpp
just recently, so I am more or less an Rcpp newbie. Since I am not
sufficiently proficient in advanced C++ (and admittedly too lazy too) to
analyze the Rcpp source code, I have some questions regarding what

Thank you for the reply. That clarifies quite a bit.
But still, it does not explain the different behavior of those examples,
does it? One moment ago, I was thinking that the L suffix might have made it
constant and hence can't be modified. Looks like I am wrong. (And fun(1:3)

Hi!
I just figured a way to deal with pointers to objects in memory which I receive
by calling whatever function of a third-party library. The problem is warp it
into a suitable object. My approach which does a nice job is:
template <>
SEXP wrap( B* const& mb ) {
typedef result ptr_wrap
16 matches
