similar to: Plot and curve inside C++

Hi I'm trying to implement something similar to the following R snippet using C. I seem to have hit the wall on accessing class slots using C. library(fPortfolio) lppData <- 100 * LPP2005.RET[, 1:6] ewSpec <- portfolioSpec() nAssets <- ncol(lppData) setWeights(ewSpec) <- rep(1/nAssets, times = nAssets) ewPortfolio <- feasiblePortfolio( data = lppData, spec = ewSpec,

Hi, I am using RInside for one of the applications that I'm using. The error that occured is as follows. When I use R.parseEval("xyz") if the parse fails then the mb_m is not cleared and hence all subsequent calls to R.parseEval fail. example: when R.parseEval("stringConcatfactoryrandom") is executed the R instance looks like this (gdb) p R $7 = (RInside &)

Hello All, A simple question. I get some return from the R in my C++ program (via Rcpp package). The result come, as SEXP and it should be a simple numeric variable. How to convert it to double? The code, what i use: stringstream ss; ss << "p <- predict(fit_ar11, n.ahead = 2, doplot=FALSE);" << "p$pred[1]"; SEXP ans; int iRet =

Estimados Se me puso en la cabeza, hacer algo en C++ que ejecute un código R, nada complicado, experimentación. Al respecto hay por ejemplo: #include <RInside.h> int main(int argc, char *argv[]) { RInside R(argc, argv); // Inicializa R // Ejecutar una expresión R R.parseEvalQ("resultado <- sqrt(16)"); // Obtener resultados desde R double

Buenas, No utilizo xcode, pero todos los compiladores tienen opciones para modificar la ruta de los encabezado y las librerías. Si no necesita librerías para compilar puede copiar el fichero de cabecera en la carpeta del programa o poner la ruta completa al fichero y cambiar los ángulos por comillas. Un saludo.

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

I am attempting to bring R-3.0.2 functionality into a project with a very large C++ codebase. The existing codebase already has a LENGTH function defined. R also defines a LENGTH function. I first compiled R as a shared library and linked it into this existing codebase, along with RInside. When I run a parseEvalQ with a linear model command it will stack dump. Looking at the backtrace, what is

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

Some formula methods for S3 generic functions use the idiom returnValue$call <- sys.call(sys.parent()) to show how to recreate the returned object or to use as a label on a plot. It is often followed by returnValue$call[[1]] <- quote(myName) E.g., I see it in packages "latticeExtra" and "leaps", and I suspect it used in "lattice" as well. This idiom

Hi, I am new to R and I'm looking to perform some method comparison analysis and would be grateful for some help regarding package installation. There is a package 'MethComp' that I want to use (http://staff.pubhealth.ku.dk/~bxc/MethComp/Courses/Sthm.2007/.) Unfortunately I am unable to install it. I have tried numerous approaches but to no avail. this is the first time I have tried to

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

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 am trying to use Rinside package in my VC++.Net program ( using Visual Studio 8.0 environment). I have downloaded Windows binary of RInside from the following link http://cran.r-project.org/web/packages/RInside/index.htm Version of RInside - 0.2.3 While compiling the program , i am getting about 69 error. Some of them are the folllowing ones. Please me in solving the following issue

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

Dear All: I have a question regarding the behavior of functions. Say I define a function that returns another function : A <- function(parameters) { # calculations w/ parameters returning 'y' tmpf <- function(x) { # function of 'y' } return(tmpf) } The value of the parameters are stored in an environment local to the function. Then I call x<- something

Dear WizaRds, I wrote a small function in R and would like to create a package. The necessary documentation is done, Rtools etc. are installed and I am still unable to complete the process under Windows. I did extensive research in the archives and read the Murdoch-Sutherland website on the Rtools and MikTeX hints. I realize that I understand only half or less of what is said there
