similar to: call r function in c++ application

I work with problems that have rather large data requirements -- typically a bunch of multigig arrays. Given how generous R is with using memory, the only way for me to work with R has been to use bigmatrices from bigmemory package. One thing that is missing a bit is interoperability of bigmatrices with C++ and possibly java. What i mean by that is API that would allow read and write filebacked

Hi all, is there a way to integrate R language within a c++ programme? That is, is there something like an R library I can incorporate in my c++ code? Thanks, Javier

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

Hello, I discovered R two years ago and thanks to the R-community I managed to write some scripts to analyze my data stored in mysql databases. The only problem is that I am the only one using R in the lab. Colleagues mainly use Matlab (but not with mysql, only with text files) but regularly come to me to get data treated with R-scripts !!!. To allow the use of my scripts by other people, my

Hi, Can anyone tell me how to embed R code in a C++ file. I am actually using a mac running on the OSX 10.6.2 and the IDE Xcode Version 3.2 and I would like to embed the basic function like geometric, binomial, normal and hyper geometric distributions in a sample cpp file. I heard about the library RInside and i have downloaded the source code for mac but i do not know how to build it in

Dear All, I would like to use - plot, - curve inside a C++ program. What R package do you recommend? Rcpp? Thanks in advance, Paul

Hi, We are a company developing a software mainly in C++. We want to integrate R inside our software in order to use mainly the engine (usual stats as mean, sigma, Pearson, outlier detection, CPA, multivariate, ...) and probably later the chart solution. Of course we don''t want to temporary write the data to some csv files and then do an ugly system() call :

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, I'm trying to call some of R's statistical functions within my C++ code, developed under VS2005, but I can't seem to find out how to do it. I tried RInside and Rcpp, but they either don't work on Windows or with VS. Is there a way to do this? Appreciate the help. Regards,

Dear all, I am testing a simple C++ function that takes a double matrix as argument and which uses routines provided by the C++ Armadillo package. I am aware of the nice capabilities of Rcpp and RcppArmadillo which helps simplifying a lot and that I have already successfully tested. However, I had a hard time trying to figure out how the coercion from a REALSPX matrix to an arma::mat =

Hi, Why doesn't R include a full Lapack but only a subset? My cda package (now archived) relying on RcppArmadillo has broken multiple times on CRAN over the past few years following updates in the underlying Armadillo library, Every time it follows the same pattern: Armadillo adds a function to solve a specialised linear system more efficiently, and the corresponding Lapack routine is not

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 am able to integrate C++ and R through RInside library. However when I use a jni call as my UI is through java it crashes at C++ side. My files are ------------------------------------------------ JNICallingClass.C: JNIEXPORT void JNICALL Java_CallR_run (JNIEnv* env, jobject callr){ std::cout << "Inside JNICALL" << std::endl; testR();

Dear R People: Could someone recommend a good c/c++ code (or Fortran) for LU decomposition, please? Sorry to bother about this. I'm trying to do some "non-R" work that requires a matrix inversion.

Is there anyway with some experience in using armadillo in R C++ extensions? My problem is the following: I programmed a function in a header looking like #include <armadillo> inline arma::vec foo(input) { ... do something return an arma::vec object } compiling this via R CMD INSTALL packagename (PKG_CXXFLAGS = -I/folder/of/armadillo and armadillo_bits in my package) I get the

Hello, I have some problems to migrate to R >3.0 my devel machine (R.2.15.2). So I decided to start from scratch with a brand new virtual machine. Downloaded latest network install of debian testing, not stable (jessie/sid, SMP Debian 3.16.3-2 (2014-09-20) x86_64 GNU/Linux) installed only with ssh-server and basic utilities (no X). Then I installed R by: apt-get install

Hi Folks, I am creating a multi-threaded C++ application that initializes RInside in one of the child thread. I would also like to access support interfaces like Rcpp::Environment in the remaining child threads, so that I could access any "R" function associated with the environment initialized. When I run my program, I always get "C Stack limit too huge" errors. I looked

Thank you for your answer. In facts, 10 threads are asked by armadillo for some LinAlg, which backs to two threads as warned. But I cannot imagine this costs so much time just for that... A deeper analysis of time spent seems to point that a large time was mainly spent on testthat and Rcpp dependencies compilation... But other recent packages depending on these also are not spending so much time.
