I was debugging a problem reported to me regarding PL/R, and found that I can duplicate it using only R sources. It might be characterized as possibly a misuse of the findFun() function, but I leave that for the R devel experts to decide. The below results are all with R-2.5.1 (I can't seem to download r-patched at the moment, but didn't see anything in the 2.5.1-patched release

Along with getting pqR to work on Windows, I've also been testing it in the context of embedded R, and in the process have found some problems with the examples given of embedded R use. One problem can be seen in R_ReplDLLinit, in src/main/main.c: void R_ReplDLLinit(void) { SETJMP(R_Toplevel.cjmpbuf); R_GlobalContext = R_ToplevelContext = R_SessionContext = &R_Toplevel;

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

Thank you for the feedback and confirmations. Interesting to see that it's also reproducible on macOS expect for Spencer; that might indicate a difference in builds. BTW, my original post suggested that timeout error was for sure detected while running Sys.sleep(10). However, it could of course also be that it is only detected after it finishes. For troubleshooting, the

I noticed that R was burning up 100% of a CPU when a call to Sys.sleep() was made. Upon investigation, I discovered that R_checkActivityEx() in src/unix/sys-std.c was putting the entire timeout (in usec) into the struct timeval tv_usec member, leaving tv_sec set to 0. I don't know about other unix variants, but Solaris requires that the timeout value be normalized (i.e. 0 <= tv_usec

list(...), I am looking for a way to interrupt R from a callback: specifically, to interrupt plotting (typically on a cairoDevice, but would be good if it worked with other devices too). Of course, one can interrupt R nicely from the console with Ctrl-C (or Esc in Rgui), but I need to do it from a GUI. Callbacks run in a new thread, so obviously stop() etc will not work. I tried to look into how

On unix, unless event polling is enabled Sys.sleep just waits in a select() call (with a SIGINT handler in place) so the elapsed time isn't checked until after the select call is complete. Rstudio uses event polling, and in particular sets R_wait_usec to 10000, which means event and interrupt checks happen during a Sys.seep call. The R GUI on macOS doesn't seem to do this (but my lldb

Hello R developers, Platform: Windows 2000. Compiler: GNU GCC - 2.95.2 (CRTDLL) I have a C function for evaluating commands using eval(SEXP,SEXP) which is included in a personal make of R.dll. (Similiar to R_Proxy_evaluate() in rproxy_impl.c) Using SETJMP to catch errors works but there is a problem. For example, the following code: if (SETJMP(R_ToplevelContext->cjmpbuf)) //

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 have gotten this sort of problem some weeks ago and have solved it with the mailing list archive. But now I have this problem again with the class library. What should I put in library/class/R/zzz.R? Everything I put in that file leads to the same error message. I'm running 0.61.3 on Linux. > knn1(train, test, cl) Error in .C("VR_knn1", as.integer(ntr), as.integer(nte),

setTimeLimit(elapsed=1) causes a timeout error whenever a call takes more than one second. For instance, this is how it works on Windows (R 3.3.1): > setTimeLimit(elapsed=1) > Sys.sleep(10); message("done") Error in Sys.sleep(10) : reached elapsed time limit Also, the error propagates immediately and causes an interrupt after ~1 second; > system.time({ Sys.sleep(10);

Dear Arnaud, Now I started to write a driver that simulates continous power breaks. (E.g. in every 30 minutes.) This could be used for testing of setup of client upsmons. I have to simulate a behaviour of a real UPS. The physical model contains an extra attribute: the charging current that needed to compute recharge time and actual battery charge during the recharge process. Can we call this

I am using rw0613b with djtools on Win95. No problem with makefiles building fortran and C dll's, plus can build R.exe with the supplied libraries (including mva). Why then do I get the following error when I try to building an existing library separately, eg... (/R-0.61.3/src/gnuwin32)$ make -f MakePkg -C ../library/mva PKG=mva make.exe: Entering directory `c:/R-0.61.3/src/library/mva'

While experimenting a bit, I found that for some reason, locking indexes with flock is problematic, but only if user is taken from passwd-file. The host system is openbsd 3.9, dovecot's configuration is added at the bottom. Authentication is from two places - first from mentioned passwd-file, then from passwd file using bsdauth (in this case, there're no problems with flock). So, if

>This mean that the specs file of Cygnus gcc is different from the >mingw32 one. OK thanks (I added main() {} as per FAQ and I got the dynload to build a dll ok) I am also interested in building the R sources as per your descriptions. To simplify things, I have removed b18 cygwin and have now installed egcs-mingw32 with your djtools as recommended. Everything seems to work OK; tools that

Hi all, I'm hoping someone more knowledgeable in Fortran than I can chime in with opinion. I'm the maintainer of the flashClust package that implements fast hierarchical clustering. The fortran code fails when the number of clustered objects is larger than about 46300. My guess is that this is because the code uses the following construct: IOFFSET=J+(I-1)*N-(I*(I+1))/2 where N is the
