similar to: Rprintf under windows?

Hello, I think this is a bug, although it is possible that I'm doind something silly. I want to be able to determine the argument name for variables passed to a generic print function suppose we have print.foo <- function(x, ...) { nm<-deparse(substitute(x)) cat("param name is ", nm, "\n") } d<-structure(1, class="foo") Under R-1.2.[2,3] >

Hi, I've found that the default options of gcc and g77 on alpha produce an executable that suffers from floating exceptions. There seems to be a problem with the configure scripts that prevents the --with-f77 option working correctly. The configure script tests that f77 is running by attempting to compile and link a dummy program - the link step seems broken on the alpha (it doesn't like

Hi Everyone, I'm experimenting with the RDCOMServer package under R-2.0.0. I'm not having much success yet - the methods im registering do show up in the registry but I'm not able to call the using RDCOMClient from another package. I'm still attempting to diagnose my problem in other ways, but though I should check to see if there are any problems have been observed by others

Hi, I've been developing an image analysis package based on R for a while now and I've had problems relating to garbage collection, so it with great interest that I've noticed the work done by Luke Tierney in this area, and I'd like to discuss how best to fit it into my package. I'll start with how my package is structured - an image is represented by an integer with a class

Hi, I've had no luck with the combination of R-2.0.1 and Rggobi/gobi (1.1-1 and 1.0-1 beta). I've tried a default configuration of ggobi, as well as one with all the plugins enabled. I'm using RedHat 9 Linux. The problem I'm experiencing is a segmentation fault when library.dynam is called from .First.lib ggobi appears to work OK from the command line. I had an earlier

Hello everyone, I've just attempted to build R-1.4 on Compaq Tru64 (I'll enclose the text from bug.report() from R-1.3.1 at the end.) The relevant part of the log is below. Any ideas? gcc -shared -o methods.so do_substitute_direct.o methods_list_dispatch.o method_meta_data.o slot.o -L/usr/local/lib /usr/ucb/ld: Warning: Unresolved: TYPEOF Rf_error Rf_protect Rf_substitute

Hi, this relates to my earlier message about external references and finalizers. I was experimenting over the weekend and now suspect that the appropriate solution to my problem will be to have a special case in the code that handles the .C call so that external references are handled appropriately - I guess that a pointer to the reference should be passed to the C code. As I've never

Hi everyone, I'm thinking about breaking up a large package I have to avoid loading some of the more specialised parts when it isn't necessary. The package is dependent on shared libraries. The base one will keep all of the core stuff like constructors etc and the specialised parts will need to access these. It is obviously possible to set the "local" flag to false, however

I'm trying to find information about how to use Rprintf with a UTF-8 encoded string, and I'm not sure what the right cross-platform usage is. I found an earlier thread about this (http://r.789695.n4.nabble.com/How-to-print-UTF-8-encoded-strings-from-a-C-routine-to-R-s-output-td4724337.html) but it wasn't very helpful. If I want to print a UTF-8 string, I can do one of the

Hello all, I am using Rprintf in a C for loop (from .Call) to print a progress indicator showing the current percent complete. The loop I am doing is an time intensive call to another function. I have noticed that Rprintf does not print to the R-window until the entire loop has been completed. When it reaches the end of the loop it suddenly prints 0 percent to 100 percent in a split second.

Dear R-devel, My g++ complains about the first argument to Rprintf being non-const char *. For example when compiling the line Rprintf("hello world\n"); the following warning is emitted: warning: deprecated conversion from string constant to 'char*' Is there a reason for the non-const? It is curious that Rf_error, which is similar to RPrintf, is const. If there is a need

I have searched through the threads and "Rprintf" causing a build error dosen't seem to be a problem for anyone else. And I've read through "R Extensions" and "An Introduction to the .C Interface to R" and there doesn't seem to be any troubleshooting for my problem. My code is straight from "An Introduction to the .C Interface to R" pg. 3. And

Hi, I would appreciate if someone could comment on this problem I am experiencing. I am writing a C++ program to be called from R. In this program, there is a verbose switch that decides whether to print some debugging info using Rprintf. On windows, things work ok. On linux, things are fine in non-verbose mode, but in verbose mode, I get error saying "C stack usage is too close to the

Thanks - I'll find another way to send messages to the main thread for printing. -Winston On Tue, Nov 21, 2017 at 12:42 PM, <luke-tierney at uiowa.edu> wrote: > On Tue, 21 Nov 2017, Winston Chang wrote: > >> Is it safe to call Rprintf and REprintf from a background thread?

Is it safe to call Rprintf and REprintf from a background thread? I'm working on a package that makes calls to fprintf(stderr, ...) on a background thread when errors happen, but when I run R CMD check, it says: Compiled code should not call entry points which might terminate R nor write to stdout/stderr instead of to the console, nor the system RNG. Is it safe to replace these calls

Dear R users, I am using R 5.1 on Windows 2000. Is there a system call or somesuch way of identifying the graphic window which currently has focus and using that information to make it the active device for futher plotting etc. I have done a quick seaqrch in R the archives using 'focus active device' but came up with nothing useful. Any information would be most welcome. Thanks in

Dear listers, I'm having a bad R day.

Dear R users, I run R on windows 2000 and windows 98 I am seeking opinion, or better still a code snippet, on what might be the quickest, not necessarily the best or preferred way, of making the Windows color selection common dialog available in R. Would it be an executable called with system() or shell() or perhaps a tcltk module or have I missed something obvious? I don't believe that I

Dear All, Has anyone worked with linking R to both ArcView and MapInfo GIS systems? My desire is to capture object selection from GIS and pass to R and to return spatially based statistical model results from R to GIS. If both could simultaneously access the same data file this would be a bonus. My inclination is to put together some routines based on ODBC linking but thought I would seek like
