similar to: Linking C/C++ GUI to R.dll

Hi, I am in the process of linking a C/C++ application to the R.dll directly. I have obtained the R source code and compiled it successfully. I have also successfully linked the R.dll directly into our application and have made calls successfully into the R.dll that are included in the sample rtest.c and in the "Writing R Extensions - The R API". The R functionality that we are

I found: max.col(matrix(c(1,3,2),nrow=1)) Is there a more concise/elegant way?

I am trying to get a dll compiled for use with dyn.load. I use R.1.7.1 under Windows. I have tried the following trivial example based on the "Writing R extensions" manual. rtest.h -------- class X { public: X (); ~X (); void Give7(double*); }; class Y { public: Y (); ~Y (); }; rtest.cpp --------- #include <iostream.h> #include "rtest.h" static Y y;

Dear R Community, I am trying to create a com dll wrapper for R in a mannor similiar to the R Com Server by Thomas Baier except that I would much rather avoid using the proxy dll ("Rproxy.dll"). Perhaps I don't really understand the reason for going throug the proxy in the first place, but it seems like an unnecessary indirection for an application which is not intended to use DCom.

People, I''m trying to run the ruby debugger against a Test::Unit::TestCase class which is a parent of a Rails class. I started my study with a simple script: # # bikle_test.rb # require ''test/unit'' class BikleTest < Test::Unit::TestCase def setup @string10 = "hello" end def test10 assert_equal @string10, "hello" end end The

Hello, I have 2700 text files in a folder and need to apply the same program/procedure to each individually. I'm trying to find how to code something like: For each file in <Folder> do {<Procedure>} is there an easy way to do this? other suggestions? I have tried to list all the files names in a vector e.g. >listfiles[1:10,1] 1 H:/Rtest/AXP.txt 2 H:/Rtest/BA.txt 3

Hi Guys, I am new to R and just trying to write a small script to automate a couple commands. But I run into the setwd(): cannot change working directory. I googled a little bit and tried all fixes/suggestions with no success. Basically I have a script that works from inside a directory with my data (/home/sean/Rtest/Data01). Now I want to modify the script to make it run from the upper directory

Hi, I have been developing a small package. It install under RedHat Linux 9.0 without a problem. However, I have a small problem under Windows XP. I am using R-1.8.0 on both systems and HTML Help Workshop 4.74.8702.0 on Windows XP. I created the package under Linux. When I try to install the package created under Linux in Windows XP using c:\rtest> rcmd install rtest I get the following

I'm not looking for an answer here, this is just a report of a peculiar event I've observed and can reproduce. I'm developing a g95 (20050129) compiled package on windows xp pro using R-2.1.1, and gcc-3.4.2 (mingw special). An older version of the F95 package compiled and ran without problems. The new version of the package includes extensive changes in the code. The package has a

Hi, I am working at a major financial institution and we would like to embed R in one of our front office application. The application is written in C/C++ so I started by trying to compile the examples in "tests/Embedding" of R 2.0.1. I have modified "tests/Embedding/Makefile" according https://stat.ethz.ch/pipermail/r-help/2005-February/064341.html and set

Because the require ''test_helper'' at the top of all the tests is relative now (it used to be something like require ''../test_helper''), you can''t just run the file with ruby anymore. And running the file with ruby is exactly what command + r does. Which means you can''t easily run your tests from textmate. The solution:

Hi, I've created a shared library from including this code (with g++ -I/usr/local/lib/R/include -I/usr/local/include -c Rtest.cpp; g++ -shared -L/usr/local/lib -o Rtest.so Rtest.cpp): void check_data (SEXP data) { int l=length (data); } But when I try to load it in R I get this error message: unable to load shared library ... ... undefined symbol: _Z9Rf_lengthP7SEXPREC How can I solve

I am compiling the Embedding examples in the tests directory and get an undefined reference. I include the make output as well as grep'd output of nm on libR.so and compiler and arch information. Do I have an improperly built R shared library or is there a problem with the Embedding tests or something else I am not seeing? Thanks for any help! George ost at

I am new to using R. I installed R on my computer (Windows) and everything things appears to be just fine. However, I have a simple script RTest.R that does a few simple calculations. When I double-click the RTest.R icon, I get an Information dialong box which says, "ARGUMENT 'C:\Documents and Settings\kgilder\Desktop\RTest.R' __ignored__" . When I choose OK, R then opens,

Hi, I want to call R from within Java, using jri as per http://www.rosuda.org/software/jri/ So I am following the instructions in the README file for JRI 0.2-4. I have run 'sh configure.win' and 'make' and they seemed to be successful. (See below for the output from make, for example.) But when I try 'run.bat rtest' (with and without R command line arguments) the output

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

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

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.
