similar to: "Use of ‘.C’ for C++ is now deprecated and will be removed in R 2.12.0"

With several versions of R 2.12.0 I have been seeing this when running R CMD build Rcpp from the SVN sources: [...] Transcript written on Rd2.log.

Hello, I've been trying to make LinkingTo work when the package linked to has c++ code. I've put dumb packages to illustrate this emails here ; http://addictedtor.free.fr/misc/linkingto Package A defines this C++ class: class A { public: A() ; ~A() ; SEXP hello() ; } ; Package B has this function : SEXP say_hello(){ A a ; return a.hello() ; } headers of package A are copied

Hi, apparently I sent my question about using R and C++ to the wrong list, ironically seeing as that list was called Rcpp. Anyway, I was directed to post my question here. To summarize my current question, I have found two commands that I want to be able to put into a package. The commands are 'R CMD SHLIB X.cc X_main.cc' and

However search for "Rcpp calling C++ functions from R" gives a lot of result but I think some of them are outdated and others don't agree with each other.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

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'm currently working on making Rcpp use the feature described here more: http://cran.r-project.org/doc/manuals/R-exts.html#Linking-to-native-routines-in-other-packages To give more context, Rcpp has for a long time built what we called "the Rcpp user library", i.e. a library we could link against user the linker. We were then producing appropriate linker flag with

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");

Hello We have a C++ class with several methods that manipulate an object. How is it possible to create several instances of that class *from R* in the C++ realm, which can then be accessed via a given name character? Symbolic example (we hope this illustrates our problem): // C++ side: class Foo{ ... } // perhaps: void my_new_instance_wrapper("the_character") // plain to see that I am

Hi, I have written a small C++ function and compile it. However in R I can't see the function I have defined in C++. I have read some web-pages about Rcpp and C++ but it is a bit confusion for me. Anyway, This is the C++-code: #include <Rcpp.h> using namespace Rcpp; // [[Rcpp::export]] List compute_values_cpp(int totalPoints = 1e5, double angle_increment = 0.01, int radius =

.Call("compute_values_cpp") Also, if you were passing arguments to the C++ function you would need to declare the function differently. Do a search on "Rcpp calling C++ functions from R" HTH, Eric On Sun, Dec 3, 2017 at 3:06 AM, Martin M?ller Skarbiniks Pedersen < traxplayer at gmail.com> wrote: > Hi, > > I have written a small C++ function and compile it.

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.

All, I'm a newbie to R and I am interested in seeing a simple example of calling a 3rd party Visual Studio generated DLL from RStudio. Does anyone have a simple example which also walks through the preliminary steps of setting up the INCLUDE path and the library path to either a DLL or LIB file ? I have tried to find an easy example, but thus far had no luck finding an example using Rcpp

Hello. I am trying to include R in an eclipse C++ project so that I can use Rcpp and Rinside. Right now I have R installed on my Ubuntu machine and both plugins are installed too. I have the directories of the corresponding .so files set in the Project > Properties > Settings Gcc c++ linker under Library Search Path. Here is the error that I'm getting when I try to build my code: >

Hi, I'm looking for a most efficient way to call an R function from C++ in a package. I know there are two functions (`R_forceAndCall` and `Rf_eval`) that can do the "call" part, but both are slow compared to calling the same function in R. I also try to use Rcpp and it is the worse one. Here is my test code: C++ code: ``` // [[Rcpp::export]] SEXP C_test1(SEXP f, SEXP x) { SEXP

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, I'd like to construct an R list object in C++, fill it with relevant data, and pass it to an R function which will return a different list object back. I have browsed through all the R manuals, and examples under tests/Embedding, but can't figure out the correct way. Below is my code snippet: #include <Rinternals.h> // Rf_initEmbeddedR and other setups already performed

Hi All, I am new to this area and use Rcpp to call C++ from R and try to build the package under Windows 7. I use Rtools and R 2.10.1 32bit. Everything works fine with me, except using R functions like "rnorm" or "runif" in the C++ code. When I use "R CMD check" the package, it always return error ** libs making DLL ... g++

I have intstalled R-3.2.2,Rcpp-0.12.2,RInside-0.2.13 on windows. I compiled the example1 of RInside in the example directory which create a RInside instance and prints "hello world". The compiler is intel c++. I included the RInside source files in the project and fixed the compile and link errors. But when run the executable file it prints some error message and quites. I debug
