similar to: Wrapping R for windows in a com dll

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.

Dear R developers, I am building an ActiveX Com wrapper for R. I have successfully implemented an Evaluate function using rproxy_impl.c and rtest.c as examples. The Com object as it stands at the moment is similar to Thomas Baier's automation server StatConnectorSrv.exe except that it does not use the Proxy. My goal it to include a couple of activeX controls in the library: One to provide a

Hello. I've dowloaded R-0.65.1 for WinNT/9X. >There is more support for (support of) ActiveX Automation via the >Rproxy.dll: see the file front-ends/readme. And where is this "the file front-ends/readme" which describes R's ActiveX Automation ? In "readme" under "r-install path\" and FAQ for Win port, no description about this. Please teach me.

Hi all, I am trying to make calls to R from an MFC application running on XP and am having problems blocking the application while the call executes. I have tried the following approaches to using R from the application (note that I set a wait cursor while R is executing). 1) call rcmd in BATCH mode using system(). This works well, except that I get the cmd window popping up... which makes the

Full_Name: Venkatesh Mysore Version: R-1.7.0 OS: WindowsXP Submission from: (NULL) (216.165.110.10) While accessing Rproxy.dll repeatedly (using the code from the (D)COM example in the R website) causes a failure in the 24th iteration. R-1.6.2 does NOT give this error. This seems to be a memory management error, that might be linked to the huge leakage difference between R-1.7.0 and R-1.6.2

Dear All, I have a pair of .cpp and .def file can be compiled using VC++ and works perfectly well in S-PLUS. I wanted to do the same for R; so I followed the guidline given in "Building from a source-code library under Windows" as much as possible and manage to compile them using VC++ and call it from R. But it gives different answer from the one called from S-Plus. I know that I did

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

I'm interested in these very questions (librsync-rsync relationship, remaining limitations of rsync, active prospects for ground-up rewrites), Google searches for rsync info have proved a little too vague due to the programs ubiquity. Much has certainly changed since this was written, could some people with knowledge in these areas could update martin's response for the state of rsync,

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

After a long processing, I was able to create a version of a small C# class that was able to emulate the rproxy by P/Invoke. This is mostly to find a workaround a performance problem of the StatConnector. It's almost work but ... I have strange memory exception when I call the print function. The variable seems to not survive from one call to the other. As there is no debug symbol for

Hi, I am getting following error messages while trying to compile: cp -p man/*.Rd ../../library/base/man rm -f ../../library/base/man/BATCH.Rd ../../library/base/man/COMPILE.Rd ../.. /library/base/man/INSTALL.Rd ../../library/base/man/REMOVE.Rd ../../library/ba se/man/RHOME.Rd ../../library/base/man/SHLIB.Rd echo done > fixRd cp -p bin/fwf2table bin/helpPRINT.bat ../../../bin echo

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 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;
