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

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

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

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(" ",

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

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

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 have not yet found anything about this is the documentation. I have W95 and W2K installed and I would like to use both, if possible. So is there anyway to config wine so that i can specify it run w95 or w2k ? Some of my programs do not run and i think it maybe because they were installed for w95. thanks -- Never in the world does hatred cease by hatred; hatred ceases by love. --

Hi, I have a linear model ("mod1 <- lm(V3~V1+V2) and I would like to get the model's prediction at values of V1 and V2 not included in the original sample. samp <- read.table("data.dat",nrows=100) attach(samp) out.poly <- lm(V3 ~ V1 + V2) If I try to use out.poly to predict values for the function I run into problems. It seems that it isn't possible to use a new

Hi, I have a matrix and I want to create a matrix that includes every nth column of the original matrix. Does anyone know how I can go about doing that ? Or if you have an idea how I can do the same thing with a data frame ? If you can just point me towards the appropriate function I would appreciate it. Thanks [[alternative HTML version deleted]]

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

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 I just upgraded to the Ubuntu 18.04 LTS, and tried to add both the "Ubuntu packages" source as well as ppa. I was not able to do this, trying to add for example: deb http://cran.cnr.berkeley.edu/bin/linux/ubuntu bionic/ or using: sudo add-apt-repository ppa:marutter/c2d4u am I doing something wrong, or just being impatient? Are there any plans to build these repos in the near

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
