...vior for system.file() is to return "" for faulty paths. I've found this behavior to be difficult when debugging, since it passes the empty path onto other functions. I initially wrote in errors myself (with code like `if(path == "") stop(?Path not found?)`), but I now use mustWork=TRUE or fs::path_package(), which errors by default. What are the general thoughts on this issue? I would love to see mustWork=TRUE become the default in future versions of R, but I would be happy to hear any counterarguments (or support!) for this suggestion. Cheers, Irene Steves [[alternativ...

Hi, on my R-3.0.2 windows (32bits) no error is thrown occurs when calling a shell command with intern=TRUE, mustWork=TRUE. Is this a intended/known behaviour? >From the source of base::shell it is clear that mustWork is only used when intern=FALSE.

I haven't been able to generate slow runs on my Linux machine, though I've had problems with slow running examples submitted to CRAN that I suspect may be caused by this. library(microbenchmark) (timings <- microbenchmark( normalizePath("\\\\some/network/drive", mustWork = FALSE), times = 1e4, unit = "s" )) boxplot(timings) Please can a few people run this code and see if they can reproduce the issue. It isn't clear to me whether this is a bug in R or an underlying OS or network problem. -- Regards, Richie

Dear all, I'm not sure whether this is intended behaviour or a bug. The path returns from normalizePath is different when the directory doesn't exist. I have included a reproducible example. path <- tempfile() missing.dir <- normalizePath(path, winslash = "/", mustWork = FALSE) dir.create(path) existing.dir <- normalizePath(path, winslash = "/", mustWork = FALSE) > all.equal(missing.dir, existing.dir) [1] "1 string mismatch" > missing.dir [1] "C:/Users/THIERR~2/AppData/Local/Temp/RtmpagA8Gx/filed5c2cd03543" > existing.di...

Hi Tomas, There has been an R CMD check error with xfun and r-devel on Windows for a while: https://www.r-project.org/nosvn/R.check/r-devel-windows-x86_64/xfun-00check.html Basically it means that the following would return TRUE before: normalizePath('a/b', mustWork = FALSE) == normalizePath('./a/b', mustWork = FALSE) but it became FALSE at some point in r-devel. I think 'a/b' and './a/b` should be treated as the same path. Does that make sense? Thanks! Regards, Yihui -- https://yihui.org On Thu, Feb 23, 2023 at 11:44 PM Hiroaki Yutani...

Hi all, A problem with tests while building R. I'm packaging R for Sisyphus repository and package build environment, by design, doesn't have /etc/localtime file present.

Looking at the code (https://github.com/wch/r-source/blob/R-3-4-branch/src/library/base/R/datetime.R#L26), could it be that mustWork = FALSE (instead of the default NA) avoids the warning causes this check error?

I haven't figured it out entirely, but it looks like there are a couple of small glitches with knitr-based vignettes and SweaveParseOptions. I posted the tarball of a package with a knitr vignette with (as far as I can tell) everything properly coded in the DESCRIPTION file (VignetteBuilder: knitr, Suggests: knitr) and the vignette itself (%\VignetteEngine{knitr::knitr}).

According to the manual, the `stdout` argument of the `system2` function can redirect output to a file. This seems to work on unix, however I can't get it to work on windows. The toy example below, no `out.txt` or `err.txt` files are created. I tried sending it to an existing file, or expand the full file path, but with no success: setwd(tempdir()) system2("whoami",
