similar to: Compiling "embedding R" examples

Hi, This question was first posted wrongly on R-help. Apologize for the inconvenience. 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 to

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'd like to use the C interface to R in a program i'm writing. as a starting point, i'm trying to create a very simple C program that uses R. i've read the R documentation on this, but i'm having trouble figuring out where SEXP is defined and how to use it. i noticed someone else on this list also tried to use the C interface, but they ran into similar problems:

Hi all! I read R Extensions manual. But still I am not sure how to call R functions from C. Would any of you give me a sample C code to show how to call R functions - for instance, time series functions - from C in the embedded way of C code? [[alternative HTML version deleted]]

I think someone posted this before, but I can't find it in the archives. I am using rsync to pull down source files to be compiled. The delete options are used to clear out any old files left over from previous. Normally this works. I've run into one case where it persistently fails. Within the directory created during compiling is a symlink to another directory, also created during

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 following the instructions on Writing an LLVM Pass on Darwin(8.7.0) powerpc. The loadable library is built. But "opt -load " gives error saying "Symbol not found". I am using LLVM 1.8. Could someone tell me how to fix it? I have tried the same procedure on Pentium4 Redhat9. Everything is ok there. So I think there must be some specific problem on Darwin that I should

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:

Hello, I've encountered two serious issues that have stopped me in my tracks, and I would be most grateful to anyone who can provide some answers. I am using the examples provided on the page "Testing the Embeddable R Library". I am writing a C application, that I want to embedd R into (I'm not interested in embedding my application in R, that's not an option). I'm

Thank you, Reid. I have applied tha patch to ltdl.c ltdl.h. The problem still exists. I looked up the symbol on libLLVMCore.a, and found three U-entries and one T-entry. However, the Darwin linker is not able to find the T-entry. Any idea? pollux:~/test jingyu$ opt -load /Users/jingyu/tools/build-ppc/Release/lib/LLVMHello.so -help Error opening

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 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;

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''ve just put a new Ruby On Rails application up for testing at: <http://rtest.openprofile.net> Open Profile can be used as a login and user profile module for any Ruby On Rails application. Its purpose is to minimize the hassle of joining new web forums (or anything else on the web that requires you to enter a user name, email addres, password twice, etc.). If it''s
