Hi, everyone, I am just trying to use Rcpp in my computer, and I would like to try a simple example from website, but R keeps reporting me error. I am using Windows XP, and has installed Rtools and GSI. Here is the response: > src = ' + Rcpp::NumericVector xa(a); + Rcpp::NumericVector xb(b); + int n_xa = xa.size(); + int n_xb = xb.size(); + + Rcpp::NumericVector xab(n_xa + n_xb - 1);

Dear all, running the example by D. Eddebuettel (http://dirk.eddelbuettel.com/blog/2011/04/23/) I get an error message. Specifically, the R code I was taking from the above example is ### BEGIN EXAMPLE ### suppressMessages(require(RcppArmadillo)) suppressMessages(require(Rcpp)) suppressMessages(require(inline)) code <- ' arma::mat coeff = Rcpp::as<arma::mat>(a); arma::mat

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(

Hola, necesito compilar un programa de tipo source (Rstan) con c++ La propia web del programa indica como hacerlo con Rcpp. Sin embargo no consigo que funcione Rcpp ni con un ejemplo básico. He seguido las instrucciones que vienen en http://tonybreyal.wordpress.com/2011/12/07/installing-rcpp-on-windows-7-for-r-and-c-integration/ Tengo instalado Rtools y los paths correspondientes, pero no

Hi all, I am using c++ functions in R by Rcpp and inline packages. The code is quite simple, but the R session always automatically crash after some running time. Does anyone here familiar with Rcpp and inline? What¡¯s the problem in the following code? I have checked the input values, no NA and other strange value exists. Thank you for your attention! > mkc <- cxxfunction(

Dear R experts, recently I started developing a Rcpp package "OpenMPTest". Within that package I want to use OpenMP, as in the following code example: // header file #include <omp.h> using namespace Rcpp ; RcppExport SEXP testOpenMP( SEXP nThreads ) ; // cpp file SEXP testOpenMP( SEXP nThreads ) { BEGIN_RCPP NumericVector numberThreads = NumericVector( nThreads );

Hello, I am trying to reproduce a code example from http://www.babelgraph.org/wp/?p=358 babelgraph when compiling the function to call the C++ code I get the following error: Error in compileCode(f, code, language = language, verbose = verbose) : Compilation ERROR, function(s)/method(s) not created!

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:

Rcpp version 0.7.0 went onto CRAN this weekend. The key new features are o inline support, taken from Oleg Sklyar's neat inline package and adapted/extented to support Rcpp as well as external libraries (see below for an example); this even works on Windows (provided you have Rtools installed and configured); o addition of a new simple type RcppSexp for importing or

I am trying to run inline/Rcpp under Windows 64. The RTools are installed on a spaceless path D:\rtools. Inlining pure c-code works perfectly. When I try the sample code for cpp in the cxx Documentation, I get: x86_64-w64-mingw32-g++.exe: C:/Program: No such file or directory The path to the compiler is correct. Obviously there is some problem with the space in C:/Program (Files). Any ideas

The solution post is here: http://lists.r-forge.r-project.org/pipermail/rcpp-devel/2012-November/004771.html In the paragraph: I did need however to install Rcpp and RInside from source, and with the same compiler used to compile qtdensity (otherwise I would get additional linker errors). As I had trouble getting the (Cygwin-based) g++ shipped with Rtools to work with Qt, I used instead the

The MinGW-w64 project, whose toolchains we use for 64-bit Windows, have made some changes to their conventions *and* removed all the older binary builds from their site. The current toolchains are not suitable for use with R 2.11.x, and I've re-packaged an older version (which is) as http://www.stats.ox.ac.uk/pub/Rtools/oldWin64toolchain.zip The most critical change is to no longer have

This would be easier if base::set.seed() accepted a value of .Random.seed instead of just a scalar integer or, new to R-3.0.0, NULL. If set.seed() returned the previous value of .Random.seed (NULL if there was no previous value) things might be even easier. People should not have to know where .Random.seed is stored. S+'s set.seed() accepts a value of .Random.seed but does not return the

Dear R users, I would like to call R from C++ and Rcpp class library already compiled are a big advantage !! I have already read the doc/PDF in the installed package 5.0 and all the posts in this forum It's possible to get the source code (RcppExample.cpp) whitout Rtools ??

I'm going to using RInside on windows enviroment. I installed all tools and packages according to Dirk's instruction. My R installation reside in d:\hli\programfiles\R-3.2.2. There's no problems with folders with spaces. The rtools is installed in d:\hli\programfiles\Rtools and MinGW in d: \hli\programfiles\MinGW. The R_HOME is set to d:\hli\programfiles\R-3.2.2. I
