Hello, I'm trying to get S4 dispatch on S3 "connection" objects. So I do : setOldClass( "connection" ) and then : setGeneric( "bling", function(object) standardGeneric( "bling" ) ) setMethod( "bling", "connection", function(object) cat( "gotcha ", as.integer(object), "\n" ) ) but I get : f <- file(

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 everyone, I just showed a friend a prototype of a site offering a service I''m trying to sell (sorry, not on the Internet yet - he saw it at my house). His comment: "Looks like it does everything, but also looks pretty ugly. You''re not going to wow anybody with that". Sitting back and thinking about it, he''s dead right - it needs some bling to make it

You might have hear this before. I just came across it today. from http://blog.beryl-project.org/ "I am running your svn and have noticed this non-tfp Beryl, what is this? It is exactly what it sounds like, an early attempt (with some success I might add) to make Beryl run without the need for texture_from_pixmap. No more black window bug from nvidia, no more Xgl, no more AIGLX. Oh

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

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

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

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

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

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

hi, i want to build a Qt front-end GUI which communicates with R, and i am not sure what i should use for the interface. There seems to be many ways: R.dll, Rinside, Rcpp, RQt, Rtools... . what is the best way? please advice. basically what i want to do is that, the Qt GUI will allow users to make selection and enter numbers, these inputs will be fed to R, already written .R files will perform

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, I am new to this list and apologize for my lack of experience in the subject. Does anyone here use RInside? I am trying to run the examples in /RInside/examples/standard such as rinside_sample_0, but I am getting the error: error while loading shared libraries: libR.so: cannot open shared object file: No such file or directory Does anyone know how to deal with this? I tried searching

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 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 &)

Bryce, embedding R varies from easy to very complex depending on what you want to do with it. If all you want is to evaluate R commands and get the result values then it is easy: you just initialize R with Rf_initialize_R() and use R_tryEval() to evaluate what you need (making sure you stay on the main thread). However, if you want to run the full event loop or even use the GUI elements then it
