New Rcpp versions 0.6.0 and 0.6.1 --------------------------------- The Rcpp package provides C++ classes that greatly facilitate interfacing C or C++ code in R packages using the .Call() interface provided by R. Rcpp provides matching C++ classes for a large number of basic R data types. Hence, a package author can keep his data in normal R data structure without having to worry about

Hi, Recently, I made an R package that used the C++ library Boost.Thread (http://www.boost.org/doc/libs/1_54_0/doc/html/thread.html) for multithreading. Previously, I have posted a question at stackoverflow (http://stackoverflow.com/questions/19651954/is-it-possible-to-build-an-r-package-which-use-rcpp-and-boost-thread-on-http), and I also asked at rcpp-devel

Hi, I am not sure how widespread this problem is, but definitely occurs for me on 64 bit Win 7 with a 64 bit R. I think I have isolated the issue (to a certain extent) in the attached Test.cpp file. Basically, I think linking with boost serialization is causing the plugin to fail. If I compile Test.cpp with line 43 (Dummy* Read() ...) commented out, I get the expected output in R: >

Hello, I'm not exactly sure how to ask this question, but let me give it a shot... Is it possible (easy) to use Rcpp Modules in conjunction with object factories? For example what I am trying to do is something like this: // c++ classes class Foo { public: void do_something() {}; }; class Foo_Factory { public: Foo * create_foo() { return new Foo(); } }; ## R Code

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: ***

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

Hi, I need to check if a string "<rh>a,b,c,d<rh>" is delimited by two "<rh>" 's as efficiently as possible(I need to do this a lot of times) and return TRUE. Can someone suggest a good technique? [[alternative HTML version deleted]]

Hi, in part of my code I need to optimize a function from within Rcpp (I followed the 2nd answer here https://stackoverflow.com/questions/48348079/applying-the-optim-function-in-r-in-c-with-rcpp). However, I found that the function leaks memory (very little, but it compounds if it's a part of repeatedly running simulation). I created a minimal reproducible example, but I have no idea where

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:

Martin, You are making your life way too complicated. There are a number of things I would do differently: 0) Wrong list. Rcpp has its down, rcpp-devel, and I basically do not read this and would have missed this were it not for luck.

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

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