Rcpp List,
Is there a recommended way to handle default arguments for
constructors? I have a class that I have created and exposed through
Rcpp Modules. I now found that I need to expose a tuning parameter
and need to modify my constructors. The standard way would be to
include just a default
Unless things have changed CUDA and R cpp don't always play nicely
together. I have an example, that I wrote up I'll try and dig it up to
send to you. The idea is that you must separate the CUDA code and Rcpp
code and compile separately and then link together. There are some header
conflicts in
Rcpp devs,
I came across what might be a bug. There are residuals that are not cleaned
up when a constructor throws an error. Consider the following.
cpp file--
#include
#include
class testError{
public:
testError(){ throw std::runtime_error("You shall not create ME!"
Is there a templated version of NA with Rcpp, or perhaps some sugar
statement, such that the following might be valid statements?
typedef double mytime;
const mytime time_unknown = Rcpp::NA;
Thanks,
Andrew

I apologize if this has been covered. I've looked and see a couple of post
relating to this issue, but I'm not sure if it was ever solved. The example
modules appear to not work, at least for me. On a related note I can't get
my modules to run either, but If I can figure out how to run the exampl

I will try and get a working example that reproduces the error, but while I
do that I hope someone knows what the error might be.

Davor,
A good place to start might be to mirror the behavior of the str in base R.
That gives quick truncated information, the kind that is helpful in
debugging.

I have an MCMC chain that runs entirely in c++ with Rcpp. It sometimes runs
for a vary long time and I want to interrupt it. Is there an efficient easy
way to include catching an interupt signal and either aborting or returning
results to that point? This might be understood well, if so I apolog

I have a default constructor.

That exposes the data3 class, but does not solve the pointer problem.

I updated to the new Rcpp 0.8.9 then added a new function to my class. It

there, but when I try to create a instance of the class I get the error:

I'm having a problem with sugar expressions that I can't figure out.
I have these two functions that are sampling and prior functions for
two different parameters of an MCMC model. BTW this is part of my big
CUDA project, so I pass these as pointers into other functions.

The init_2 is unnatural. I would prefer the new syntax. As I have to
code that is relying in the init_2 at the moment I'm fine with
switching it out. Does this mean that we will be able to expose
multiple constructors?

My two cents on this. Since I'm working on CUDA code, and CUDA for
some reason does not like Rcpp I have to have a separate cpp file
exclusively for the RCPP_MODULE, that does not include any cuda code.
Then things are resolved in the linker. I'll always put RCPP_MODULE
in a cpp file for my work.
Figured it out. The definition for data3 is in a namespace, so it
could not find the member functions.

There is no initSwabs with only one parameter, is that what this is looking for?

I'm getting what I assume is a basic error, but I'm not sure what I'm doing
wrong.

I've attached the file of the errors now. I've also tried to change the
order of includes without much success.

Doesn't sugar require Rcpp vectors, which encapsulate R SEXP vectors? If
that is the case you really cannot separate them at all since there is a
direct dependency on R.

I have a class that I am building that I want to interface through Rcpp, but
when I just include Rcpp, even without any Rcpp code included. I get several
errors that appear to be template problems. What is going on here? I've
attached the error output file.
It compiles fine without including Rcpp
te as good as vim. I'm right now developing on Ubuntu, since CUDA works
much easier on it.

Is it possible with Rcpp Modules to have a class that does not have a
default constructor? Consider this example
-
#include
#include
class c1{
private:
int n;
int * x;
c1();
public:
c1(int n):n(n){}
int getn(){return n;}
};
RCPP_MODULE(c1){
using namespace Rcpp;
class_("c1")
.property("n",&c

named vector into an equivalent structure would be
helpful.
