Anyone knows a way to re-throw a caught interrupt condition, so that it behaves just like the original one? I.e. no error message is printed, but the execution is stopped of course. With just calling stop in the error handler, it prints the error message, or, if there is no error message (like in the original interrupt condition), another error happens. tryCatch(Sys.sleep(100), interrupt =

The first of Suharno's examples can be viewed that way, because R under ESS is not a "slave" in the technical sense, just a situation where you do not want keyboard input to be echoed. "Non-echoing" might have been better language though. The 2nd example really is of the master/slave variety, and to my knowledge nothing to do with echoing, so looks like a

SVN revision replaces "slave" with "no-echo" in R devel. In each of the following, "no-echo" is rather strange to me. - src/gnuwin32/README.Rterm 3) As a no-echo process for ESS mode in NTEmacs with flag --ess. - src/library/grDevices/src/qdCocoa.m /* the no-echo thread work until this is NO */

This is a not too old R-devel on Linux, it already fails in R 3.4.4, and on macOS as well. The tar file seems valid, external tar can untar it, so maybe an untar() bug. setwd(tempdir()) dir.create("pkg") cat("foobar\n", file = file.path("pkg", "NAMESPACE")) cat("this: that\n", file = file.path("pkg", "DESCRIPTION"))

Source versions would only have been available with a nondisclosure agreement, and relatively few copies would have been distributed in source. There was a small but valuable "beta test" network, mainly university

I'm just curious. Why making "if" generic is even more dangerous? Best, Da On Sat, Mar 4, 2017 at 1:22 PM, G?bor Cs?rdi <csardi.gabor at gmail.com> wrote: > `!` is a generic, `if` is not.

Dear all, I would like to write some tests for my R package, and the usual 'tests' directory seemed like a good solution, but there is something I cannot understand. It is possible to supply .Rout.save files with the expected output for the tests, which is great. But since the tests are not run with R --slave, the expected output needs to contain all the extra output from R, e.g. the

Was this resolved upstream or is this something that R should/could fix? If the latter, could this also go into the "emergency release" R 4.0.2 that is scheduled for 2020-06-22?

Yes, indeed it seems that old OpenSSL versions cannot handle

I don't think anyone denies that you *could* make an EXE to do all that. The discussion is on *how easy* it should be to create a single file that contains an initial "main" function plus a set of bundled code (potentially as a package) and which when run will install its package code (which is contained in itself, its not in a repo), install dependencies, and run the main()

A colleague is receiving some data from another person. That person reads the data in SAS and it takes 30s and uses 64k RAM. That person then tries to read the data in R and it takes 10 minutes and uses a gigabyte of RAM. Person then goes on to say: It's not that I think SAS is such great software, it's not. But I really hate badly designed software. R is designed by

Dear All, in some functions of my package, I use the Matrix S4 class, as defined in the Matrix package. I don't want to depend on Matrix, however, because my package is perfectly fine without Matrix, most of the functionality does not need Matrix. Matrix is so included in the 'Suggests' line. I load Matrix via require(), from the functions that really need it. This mostly works

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

Sorry for not reading carefully and thanks for confirming problem with Rscript too.
