similar to: Problems with embedded R, ReplDLL

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

Hi All My C++/linux program uses Rf_initEmbeddedR to start R and then calls some R functions. Now I try to port it to Windows. Give the fact that Rf_initEmbeddedR is missing in Windows, I try to use the implmentation in Rserve by Simon Urbanek. When I build in MS Visual Studio, I get the following linking error error LNK2019: unresolved external symbol __imp__putenv referenced in function

Dear R-developers, even though I may not be the first one to encounter the problem described below, I would really appreciate some help or a link to a forum where this topic is being discussed. Probably I am simply misinformed on the usage of structRstart but see for youselve. I did check multiple forums and the whole internet on the topic without success. I am using the shared library version

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

Hello, I would like to establish top level condition handlers and restarts, so that I don't explicit calls to withCallingHandlers and withRestarts in many places: For example : > customError function( message ){ err <- simpleError( message ) class( err ) <- c( "customError", class( err) ) err } > withCallingHandlers( { signalCondition(customError(

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 have some problems with the rtest.c example under gnuwin32\front-ends I am able to build it and it runs without problems. But when I give it a command that isn't defined it crashes. This only happens when I build it in then complicate case where it uses R_ReplDLLdo1(). Any help would be appreciated. Ps. Sorry my poor English

Hi everyone, I'm trying to create a small C++ program which embed R, but I'm having problems when I try to do it on Windows 64 bits. I have created a minimal reproducible example which is just the src/gnuwin32/front-ends/rtest.c file with the R_ReplDLLdo1() loop, the only difference is that I set the interactive mode to TRUE. Here is the cpp file:

Dear list, I am trying to implement a publish-subscribe mechanism in for an embedded R interpreter. But somehow my registered closures seem to get collected by the GC, even though I have protected them. I have reducted my code to the following sample. Sorry if it is a little verbose. The first couple of call of calls still work, but at some point one of the callbacks (callback1 in my

Hi - I wrapped R.dll up using somebody code online (see below). I am comparing R on .NET IPC with R(D)COM. I got it all working. Except, I realize that in my client code of the IPC remoting, if I call 'plot' function in R via EvaluateNoReturn, I don't seem to see any results on the R plot window (although the window pops up). Is there anything to do with the code of R.dll wrapper

Hello, I've been playing around w/ the new dynamic C symbol stuff (thank you for doing that!) in the, um, 5/11/01 R-devel package and, unless I've missed something incredibly obvious, there doesn't appear to be a mechanism for registering functions of an embedding executable. It seems like this would be a Good Thing to have. Since I'm doing most of my work in Windows at the

I'm running some code in R64 on a Mac OS 10.6.8 that calls a C program through the dyn.load() function. The code hangs after several days of computation, and I've having trouble locating the problem. Can anyone decipher this info from the error report, and tell me if this is a problem in R64, or in the C code? Thanks very much in advance. A few hints: "pa" is the name of the C

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

Dear r-helpers, I have been trying to invoke R from Java in a Windows 2000 computer (unfortunately). All my environment variables seem to be properly set, everything seems to be in order, but I obtaining a Fatal error: unable to open the base package error window.

Here is a patch that does TIS auth via PAM. It's controlled by a switch in the sshd_config. You'd use it by having a PAM module that sets PAM_PROMPT_ECHO_ON. eg, you could use it with pam_skey or pam_smxs. The patch is against the 2.9.9p2 distribution. I'm not on the list, a reply if this patch is accepted would be great. (But not required, I know some folks have a distaste for
