similar to: Getting R to emit an image file as a pipe or Base64 strea m: Mac OSX 10.3 - R 2.0.1

Hi All, Anybody know how to make R emit base64 encoded text in some way that perl can grab it, instead of planting a file on your harddrive when calling JPEG or PNG? I've managed to get these scripts to work and put a file on the harddisk #!/usr/bin/perl -Wall # by jin kee. a simple script to demonstrate # the needed steps to get R to emit a jpeg. use strict; my($callR, $callRold); # need

Dear lists, I want to construct a loop in R, but don't know how to do it. I can do it in SAS, but I prefer in R (which I am hoping I will off SAS for good soon). Could anyone help me to convert the SAS codes to equivalent R codes. Basically, the following codes were written to establish the sire gametes or phases for daughter design for one markers two alleles. Here are the SAS code: do

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 process is of course still running happily. Terminal 2

Unfortunately --interactive also makes the session interactive(), which is bad for me, as it is a background session. In general, I don't want the interactive behavior, but was wondering if I could send as SIGINT to try to interrupt the computation of the background process, and if that does not work, then I would send a SIGKILL and start up another process. It all works nicely, except for

Yeah, I get that they are async. What happens is that the background process is not doing anything when the process gets a SIGINT. I.e. the background process is just listening on its standard input. AFAICT for an interactive process such a SIGINT is just swallowed, with a newline outputted to the terminal. But apparently, for this background process, it is not swallowed, and it is triggered

Dear All, I was wondering whether any one knows of a matrix bending function in R that can turn non-positive definite matrices into the nearest positive definite matrix. I was hoping there would be something akin to John Henshall's flbend program (http://agbu.une.edu.au/~kmeyer/pdmatrix.html), which allows the standard errors of the estimated matrix elements to be considered in the

Hi All; This problem has come about from trying to learn some of the review practices recommend by rOpensci. One of them is to use the package goodpractice. After installing goodpractice, it kept failing on my own packages which are under development, and I was concerned something was funny in my own , so I have a fork of the package rerddap, and I tested goodpractice on that. I get the

withr:::set_makevars() can give that error if the makefile named by the 'old_path' argument (default "~/.R/Makevars) contains more than one definition of a variable of the form 'name=value'. You can see what file it is reading and its contents by using the trace() function: trace(withr:::set_makevars, quote({ cat(old_path, "\n"); writeLines(paste0(" ",

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

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();

awesome, merci Dirk! and my apologies for not scrolling down better, I failed to see that the 18.04 update was linked to the R 3.5 issue . Further, please forgive my impatience, but I was very curious to see if the package 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

Hi, Is there any tool to check if there is update version of a package available? I look for things alike YUM for linux? YD

Hi, I have come across a csmith generated test case that made the MachineVerifier spit out: *** Bad machine code: Multiple connected components in live interval *** Having looked at what this might mean, it seems that ConnectedVNInfoEqClasses::Classify() was called on the LI in question by the verifier, and that it returned two equivalence classes, instead of just one, which is demanded by

A Simon pointed out the interrupt is recorded but not processed until a safe point. When reading from a fifo or pipe R runs non-interactive, which means is sits in a read() system call and the interrupt isn't seen until sometime during evaluation when a safe checkpoint is reached. When reading from a terminal R will use select() to wait for input and periodically wake and check for

Hi everyone, I've been opening up R 2.0.1 from the dock and then starting the Mac OSX X11 server. After that I call >jpeg("test.jpg",plot(rnorm(10))) and r pops up a quartz window with the appropriate graph in it and puts a file called test.jpg into the HOME which is 0kb in size and is completely empty. There is no error message. I've tried >png("test.png",

Gabor, I think you're talking about two independent things. You can interrupt the computation, no question about that. It's just that if you send an interrupt while you're *not* doing any computations, it will be signaled but not raised until the interrupts are checked since there is no one to check it. This goes back to my original response - the interactive REPL calls

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.

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
