Hi, I am a newbie to Rcpp packages, and got problems in having basic set-ups for Rcpp under windows xp. Here is the list I have done. 1) installed Rtools and have no problem in compiling .c file. 2) installed Rcpp packages 3) set enviroment variables 'path' to make C:\Program Files\R\R-2.12.0\library\Rcpp\include\ searchable The sample C++ code I used is from the original website:

Hi, Im not sure if this is the right place to post this. I am using Xubuntu Karmic Koala and am trying to use the Rcpp package. I am testing it using a simple code that takes in a vector and adds 1 to each element: #include <Rcpp.h> // This file takes in a vector and adds one to each entry RcppExport SEXP addone(SEXP vec){ // create a local copy of vec Rcpp::NumericVector

Dear R-Developers, I just started learning how to use Rcpp. Earlier while using it, I encountered an error as shown below: file74d8254b96d4.cpp: In function ‘Rcpp::NumericVector foo(Rcpp::NumericVector, Rcpp::NumericVector, Rcpp::NumericVector, Rcpp::Function, Rcpp::Function)’: file74d8254b96d4.cpp:10: error: invalid operands of types ‘SEXPREC*’ and ‘R_len_t’ to binary ‘operator/’ make: ***

But I though it was a developers of the rcpp-package. So it is ok

I would go to the source, in this case Dirk Eddelbuettel's (I hope I spelled it correctly) documentation for Rcpp: http://dirk.eddelbuettel.com/code/rcpp/Rcpp-attributes.pdf Note that you need to do sourceCpp("logistic_map.cpp") in R instead of building and dyn.load()-ing the object.

Hello, I have recently been doing some research regarding how to successfully save and load Rcpp Objects ( objects from modules ) for future use, but with little success. For example, to use the example package (from package skeleton) in Rcpp: >library(Rcpp) >Rcpp.package.skeleton("rdevelhelp", module=TRUE) ... > q() // install rdevelhelp using R CMD INSTALL // load new R

I have spent some hours browsing the RInside and rcpp documentation, lots of it; but ... as a programmer of C++ since 1990, on both Windows and Unix ... ( Solaris and Ubuntu, and Mandrake/Mandrivo Linux); I see a minor problem ...... Where is the rcpp.h header file?? The below code fails to compile as the RInside.h header file references the rcpp.h header file, which is not included with

Martin, You are making your life way too complicated. There are a number of things I would do differently: 0) Wrong list.

Hi all, I'm new to R and Rcpp, and I'm trying to learn Rcpp with the simplest code possible. My goal is to be able to call R functions from C++. The code I'm trying to run is: #include #include #include #include int main(int argc, char* argv[]) { Rcpp::NumericVector v(1); return 0; } It compiles and links fine. However, as soon as I run it, it segfaults. The following is

Hello to everyone I have written a small c++ function of type double function(double,double); and i want to export it in R using RCPP. After some trials i have realized that the only way i could do it working is to declare the function as void function (double x, double y, double result) and pass the result with RCPP Can you please tell me if this is the only way out? And if this is the case how

.Call("compute_values_cpp") Also, if you were passing arguments to the C++ function you would need to declare the function differently.

Friends I am looking at Rcpp and I am a bit stuck on a simple matter. (I am calling R from c++, if there is a better way...) Given this simple example using the TTR package and the SMA function which returns a simple moving average.... Rcpp::NumericVector rv; for(int i = 0; i < 100; i++){ rv.push_back(rand()); } Rcpp::Environment TTR("package:TTR");

Hi, I am Linux Ubuntu 9.04 user. I'm using R-2.6. Actually, I am developing R package for reading/writing 3D images. I needed to use the R package Rcpp in order to make profit of available C/C++ codes. My problem is that my C code is not able to include the Rcpp.h In fact, when I run this command R CMD build rply, I got the following error message in the file

I am running into a wall getting my system to work with rcpp and inline. Following Dirk's advice on stackoverflow, I hope someone is able to help me. My steps were to install MinGW 32 bit first, then installing Rtools, I disabled MinGW's entry in the PATH. I am trying to get the following code to work: library(Rcpp) library(inline) body <- ' NumericVector xx(x); return wrap(

Hello My colleagues asked me to install "R" with module "shiny". R version 3.0.1 compiled fine on Solaris 10 and is running well. I tried to install "shiny". With the dependencies "Rcpp" should be installed before. But the compile step did fail. See below. The initial error message is "Error in dyn.load(file, DLLpath = DLLpath, ...) :" Before

However search for "Rcpp calling C++ functions from R" gives a lot of result but I think some of them are outdated and others don't agree with each other. Can you point to a specific good on-line guide for me? Regards

Hi, I am trying to make a package B that extends another package A. Package A uses Rcpp, and I want to extend a class X used there. So package A has src/X.h and inst/include/X.h class X { ... } src/X.cpp X::X( arguments ) { ... } My package B wants to do this: DESCRIPTION [...] LinkingTo: Rcpp, RcppArmadillo, A Imports: Rcpp, RcppArmadillo, A src/Y.h class Y: public X { ... } src/Y.cpp

Hi. Here is a piece of cpp code. It works, but I do not understand the rational for the use of "R::dpois" to call the function dpois since in the examples I have always found directly "dpois" or "Rcpp::dpois" that both do not work in my code. Could anyone be so patient to explain me why should it be like that? Thaks a lot, Enrico #include <Rcpp.h> using
