A common need in R frontends is to provide some sort of read, (parse), evaluate, print loop. However, there are also a number of points where frontends may want to differ from the standard REPL as available e.g. in R_ReplDLLdo1(). First some thoughts on what is needed, and what is already there, or missing. If you want to skip over this, a short summary is provided in the second half, below

When I try to load winelib dll I get an error message: "err:module:MODULE_LoadLibraryExA Loading of native DLL <dllname> failed (error 193), check this file." The error message is printed for call: DllHandle = LoadLibrary(DllName); This happens even when I try to load standard Wine dlls, like dlls/msisys.ocx.so Did I miss something obvious? Thanks, Andriy Palamarchuk

I am working on embedding R into some visualization research programs. Can any point me to a collection of embedded and standalone R/C/C++ examples? The documentation is to terse for me to figure out how to develop this and I am looking for some simple examples to study. Thanks and best regards, EBo --

All, Looking for some help here. Not finding anything on the net that looks the same as what I'm seeing. Running Solaris 10 Sparc, on a Sunfire 5220, 16Gb of RAM. Samba version 3.4.5 and using ZFS file systems with user quotas. All cifs clients shares to this server freeze after about 10 to 15 minutes of connectivity. Only fix is to restart samba. I'm not getting any errors

Wine always give errors when it tries to start on xser ver ":1" because it always tries to connect to ":0.0". I know that DISPLAY is set correctly: Xlib: connection to ":0.0" refused by server Xlib: Client is not authorized to connect to Server

In src/main/gram.y, the documentation for R_ParseVector has a wrong signature: SEXP R_ParseVector(TextBuffer *text, int n, ParseStatus *status) should be SEXP R_ParseVector(SEXP text, int n, ParseStatus *status) In addition, the two occurrences of "IOBuffer" in the documentation should be replaced by "IoBuffer". version.string = Version 2.3.0 beta (2006-04-14 r37779)

Thanks, bjornr, however your suggestion to try: wine "C:\Program Files\intuit\qbtimer\qbtimer.exe" gave the same result as the other command lines I tried. All invoke the qbtimer program and all get the same error from qbtimer: Can't find timer file "Files/intuit/qbtimer.exe" ... So wine properly finds the qbtimer.exe file. The error arises after the program is

Dear All, I tried to write a C++ program that uses R internals and I encounter "undefined reference" error when linking to libR.so. Here is an small example of the program test.cpp: extern "C" { #include <config.h> #include <IOStuff.h> int main(int argc, char** argv) { R_IoBufferInit(&R_ConsoleIob); return 0; } } I built it using: g++ -o test

Dear R developers, i've got a question concerning an embedded R instance. I called the initialization routines as seen in the "writing extensions" guide (Rf_initialize, setup_Rmainloop and R_ReplDLLinit). I also changed the function callback pointer of readconsole and writeconsoleex to my local functions. when i call mainloop there is no problem and the commands are evaluated

Dear List, When I try to parse code containing newline characters with R_ParseVector, I get a compilation error. How can I compile code that includes comments and newlines? I am using the following: void* my_compile(char *code) { SEXP cmdSexp, cmdExpr = R_NilValue; ParseStatus status; PROTECT (cmdSexp = allocVector (STRSXP, 1)); SET_STRING_ELT (cmdSexp, 0, mkChar (code));

Hi gurus, After an unsuccessful scrabble through the documentation and Jon's excellent search facility, I am no wiser as to how R recognizes an incomplete command line and politely raises its hand for more. The help page for parse gives no indication that it does anything more than spit the dummy when fed an incomplete command line, but something in there must recognize such ellipsis.

As suggested, I checked that I was getting wine of the right vintage, and as you see below, I indeed seem to have the version designated by the codeweavers rpm name I downloaded (codeweavers-wine-20011108-5.i386.rpm): [cafl@emma cafl]$ which wine /usr/bin/wine [cafl@emma cafl]$ /usr/bin/wine --version Wine release 20011108 Wine exited with a successful status [cafl@emma

Hi, i visited wiki.samba.org and read the "Release Planning for Samba 3.2" information and the "Release Planning for Samba 3.3" information. So my question is: Is samba 3.2 development stopped and all concentration given to Samba 3.3 ? Because there isnt any further release note available for 3.2, but instead there are some notes for 3.3 ? Bye and thanks for your

Hello! This is my first post here. I came across the very same problem. It can be reproduced within modified tests/Embedding/RParseEval.c Actually this example has another issue, namely it doesn't wrap everything in R_ToplevelExec . This is a major show stopper for newcomers as that function is barely mentioned anywhere and longjmp into terminated setuploop function followed by R_suicide

Hi all, I am using R-3.0.1 under Linux platform to embed R into my C++ code. I am facing an error while executing more than 1 R-expressions parallelly. I am executing round(X) and abs(X) parallelly on a set of 50 input rows which resulted in segmentation fault after getting the following errors. Error: unprotect_ptr: pointer not found Error: argument to 'findVar' is not an environment

Hello, I've been using R embedded in PL/R (R procedural language handler for PostgreSQL, http://www.joeconway.com/plr/) very successfully for several months now. A sincere "thank you" goes to the R development team for such a great product. I have a question I'm hoping someone here can help me with. In order to get the required functionality out of PL/R, I've had to

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

Earlier I posted the message below to R-announce. Please, let me appologize for this mistake, it was not intended. The solution was provided by Duncan Murdoch who passed on a message he recieved from Brian Ripley which informed me that settimg R_Interactive to 1 changes the default behavor of aborting on an error. Thankyou, Don Wingate. -----Original Message----- From: Don Wingate
