The fix should just be to add
#include typeinfo
On top of the file somewhere.

Sure. Something like that, typeinfo is pretty orthogonal to features of the
other includes, so no issue of header order.
While you're there, does R CMD check Rcpp work fine ?

I dont know. This looks like a deeply hidden problem.
Maybe you can enable some rcpp debugging by adding
#define RCPP_DEBUG_LEVEL 1
Before you include Rcpp.h, this will give you verbose output, maybe this will
help locating the issue.

for( int j=0; jy.size(); i++, j++) z[i] = y[j] ;
I know it is not a big deal for people to write this code, but for
example this does not handle the names of the elements, ... and
internally I can use more efficient code

there is memory you'd like to free ?

Can you show some examples ? The intention is (and has always been) to
hide the macros from the R API so this is not expected.

If this does not work, then you can do some debugging as indicated by

Z(1, 0) = 223;

Also, including RcppArmadillo.h after Rcpp.h is wrong. You should only
include RcppArmadillo.h.
I should do something so that the compiler tells you this.

That looks very similar, if not identical to what dgCMatrix uses. Can
you direct me to a constructor where I could feed such information ?

Ah. One thing I could do is leverage this:

#include ARMA_INCFILE_WRAP(ARMA_EXTRA_SPMAT_PROTO)
#endif
Not sure how yet.

Romain:
In general it is very slow to insert non-zero elements into this
format. In the worst case the entire structure must be copied and
extended for each insertion. We have to keep telling people about this
when they tell us that sparse matrices in R are so slow to work with.

The argument for as is a SEXP :
template typename T T as( SEXP m_sexp)
and NumericVector::operator[](int) gives you a reference to a double

You are calling back to R using Function. This is expensive.
What is ker ? Can you implement it in C++. This is a wild guess, but
that is I think where the bottleneck is.

Your patch looks good and careful, nice work. At a first glance, tThe only

maybe this was something

If anyone wants to fix it before me, it is essentially just about
