similar to: Possible bug in Rcons_vprintf

Hello all, I would like to request that getConnection() and the struct Rconn declarations be added to the R embedded interface. Here's why. It's common in CGI scripts for web applications to direct stdin, stdout, and stderr map to reading from the browser, writing to the browser, and writing to a web log file respectively; very nice and neat. However, things get a little hairy once

I would like to redefine some R print functions (Rprintf for example) so that they don't print to stdout, but save the output in a global string array. I can compile and link my definition of Rprintf into a library and load it with dyn.load. I don't get an error message, but afterwards the original function is still valid, my new version isn't executed. Is there a way to change R

Dear list, I am trying to embed R into a C++ program. After some tinkering, reading the documentation and browsing the source code I have this more or less working. A very very condensed and very simplified version of the code is included below. The program can create plots. However, after the plot is initially drawn it is no longer updated. When scaling or updating the plot the window becomes

I'm seeing a segfault on x86_64 Linux with the following code: desc = read.dcf("BAD") con = gzfile("test.gz", "wt") write.dcf(desc, file=con) close(con) where BAD has a long field (see below for example). The crash happens inside dummy_vfprintf. I think the issue is that the va_list ap is modified by the first vsnprintf call

I maintain the geometry package, which integrates the Qhull C library (http://qhull.org) into R. The Qhull function I hook into requires an open FILE handle as one of its arguments. I had set this file handle to stdout, but now R check NOTEs the presence of stdout, and the CRAN maintainers asked me to get rid of these NOTEs. Including the following defines means the checks are passed on CRAN:

Hi! I have an application embedding R. For that of course, it is great, that since R 2.1.0 the pointers in Rinterface.h allow me to override some callbacks, easily. However, after implementing/overriding a couple of those, I'm a bit confused about when exactly they get called. So, here are a few specific questions: ptr_R_EditFile: I can find exactly one point in the R-sources where

Hi all, I'm working on a GUI frontend for R, and I'm looking for a good way to catch all warning- and error-output. The reason for this is mostly, that I would like to know, which sections of the output are "normal" output, warnings, and errors. This would allow for some nice features, such as highlighting warnings and errors in a different color, or popping up a message

Dear R developers, this mail is basically a summary / clarification of some previous mails I sent to this list last week (subject "Catching warning and error output"). Duncan Murdoch pointed out that these were badly organized, and suggested I repost, collecting the main points previously spread out between several mails. Problem statement: In an application embedding R, I would

Hi I try to develop a R interface to a set of C routines, in order to produce a R-package on Geostatistics. My C-code uses interaction with the user as I use printf and gets statements. I develop the code in a LINUX environment and do not face any problem having the questions and answers routed on my current Terminal. When I tried to port the package on Windows, the problems began. No message

Curious to know if this warning is expected behavior, and if so, what is the recommended way instead: > dput(letters, file = stderr()) c("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p",

Hello, I'm evaluating this expression expression({ for(x in 1:5){ .Call('rh_status','x') }}) a million times from a program with R embedded in it. I have attached reproducible code that crashes with Program received signal SIGSEGV, Segmentation fault. 0x00002b499ca40a6e in R_gc_internal (size_needed=0) at memory.c:1309 1309 FORWARD_NODE(R_PPStack[i]); Current language:

Hi, I'm trying to understand (mostly from the R-exts manual) how to use the callbacks declared in Rinterface.h. As a first attempt, I'm trying to redefine ptr_R_WriteConsole in a very trivial manner. Here's my code: --------------- $ cat altr.c int Rf_initialize_R(int ac, char **av); #define R_INTERFACE_PTRS 1 #include <Rinterface.h> extern int R_running_as_main_program;

Hi, I have an R script that takes its input in the form of command-line parameters. It works fine, but R complains about every unknown arg with the "ARGUMENT %s ignored" message, and this goes to stdout instead of stderr because R_ConsoleFile isn't set yet. Is it really necessary to process all command line args before setting R_ConsoleFile? It seems that only Aqua systems care

I'm in the process of porting R header files to Delphi. The short term aim is to be able to make calls into the R.dll from Delphi; the longer term aim is to play around with writing a Windows front-end with some of the features of the S-PLUS environment (e.g. scripts), and other features from other IDEs I've used (e.g. watch windows, popup values of variables selected by mouse, etc.)

I have been using R under Linux for more than a year and I think that it is great. Last week, I downloaded the binary Ms Windows version. I wanted to test it for my students. Our labs are under Bill Gates. I am not happy but I can do nothing. R worked. But, I could not use the dyn.load command with some dll built with one of the ports of gcc for windows 95/nt (I used the ecgs-mingw32 ports
