My RcppArmadillo code is structured with a .cpp function that calls a
group of enabling .cpp functions. The .cpp function returns SEXP
arguments and is wrapped in the macros BEGIN_RCPP, END_RCPP to promote
C++ errors to R. The group of other functions called are structured as
void return (passing

Dear Rcpp Experts,
I have encountered two issues when modifying an object within C++
function. See the code below:
##
library(inline); library(Rcpp)
D <- matrix(rnorm(4),2,2)
src3 <- '
NumericMatrix xD(D);
xD[1,1] = 100.0;
return xD;
'
passRef <- cxx
To chime in about Romain's comment about recognizing more types. I would
love a more robust exception handling. I think I already mentioned that but
sometimes throwing a std::exception can be very expensive. something a
little bit more robust would be very helpful. For example, with the

Thank you! Now applied as rev 2811.

By passing a exception class that inherits from std::exception, see a C++

Hello,
That is because you are not throwing an exception, but a "const char*" and
END_RCPP does not recognize this type. Maybe it should.
You can either create your own exception class or use one from the standard
set: http://cplusplus.com/reference/std/exception/exception/

Dear Rcpp experts,
I have got another problem with the throw of exception in C++
channelled into R. Apologies but these codes are not reproducible: I
didn't succeed to use the BEGIN_RCPP ... END_RCPP commands with the
inline-package. Help regarding this would be also welcomed.

Hello,
Following Gabor's thread yesterday, I looked into R source code and figure that
we don't need to test for NA when using numeric vector. See this:
require(inline)
require(Rcpp)
pl <- cxxfunction( , '
return List::create(
NA_REAL + NA_REAL,
NA_REAL + 1.0,
1
Perfect. You were correct. It was just to do with my compiler. It worked.
For future reference, my compiler's version is:
gcc 4.4.3
Cheers,
Cedric

Dear Rcpp experts,
I've got another problem related to Rcpp Sugar. Basically, I would
like to have the same functionality that you get from R's vectors,
where binary operations with scalars are automatically interpreted as
elementwise operations. See the following code and error message:
