Hi, I am able to integrate C++ and R through RInside library. However when I use a jni call as my UI is through java it crashes at C++ side. My files are ------------------------------------------------ JNICallingClass.C: JNIEXPORT void JNICALL Java_CallR_run (JNIEnv* env, jobject callr){ std::cout << "Inside JNICALL" << std::endl; testR(); std::cout << "ENd of JNICALL" << std::endl; } ------------------------------------------------- CppCall2R.C void testR(){ Rcpp::...

OK, I managed to create an example without callr, but it is still somewhat cumbersome. Anyway, here it is. Terminal 1: mkfifo fif R --no-readline --slave --no-save --no-restore < fif Terminal 2: cat > fif Sys.getpid() This will make Terminal 1 print the pid of the R process, so we can send a SIGINT: Terminal 3: kill -INT pid The R proc...

...y wake and check for interrupts. In that case the interrupt will probably be seen sooner. If the interactive behavior is what you want you can add --interactive to the arguments used to start R.

Can you give an example without callr? The key is how is the process stated and what it is doing which is entirely opaque in callr. Windows doesn't have signals, so the process there is entirely different. Most of the WIN32 processing is event-based. Cheers, Simon > On Apr 30, 2019, at 4:17 PM, G?bor Cs?rdi <csardi.gabor...

Hi All, I realize that this is not a really nice reprex, but anyone has an idea why a background R session would "remember" an interrupt (SIGINT) on Unix? rs <- callr::r_session$new() rs$interrupt() # just sends a SIGINT #> [1] TRUE rs$run(function() 1+1) #> Error: interrupt rs$run(function() 1+1) #> [1] 2 It seems that the main loop somehow stores the SIGINT it receives while it is waiting on stdin, and then it triggers it when some input comes...

Hi, I have a LLVM IR file generated for a different source language (Not C). I have added a rand() function in it to generate random numbers. I compiled the .ll file to .o using clang. However, when I execute the .o file all generated numbers are zeros. How should I link the .ll file with the standard library for the clang to generate the random numbers? Thanks -Shilpa -------------- next

...tidyverse could be installed: I have the impression that it is short of being installed, missing just a few simple packages (with no apparent non-R dependencies). Indeed, a first naive look shows following unavailable dependencies for tidyverse: ## missing for tidyverse: modelr (ok!?) reprex: -callr -debugme -covr -rex (ok!?) -rmarkdown (ok!?) rvest: selectr (ok!?) I hope that these package could be considered in a near future Michael? Thanks! :-) Best, Matthieu 2018-05-05 16:02 GMT-07:00 Dirk Eddelbuettel <edd at debian.org>: > > Salut Matthieu, >...

Hi, Does any one know if it is possible to create an R script that can use command line parameters. I can execute an R script from the command line, but I cannot figure out how to pass parameters to the script. The only resources I have found seem somewhat involved or incomplete. Any help is appreciated. Akintayo [[alternative HTML version deleted]]
