[Rd] Redirect system2 stdout to a file on windows
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, stdout=out.txt, stderr=err.txt) file.exists(out.txt) Am I doing something wrong or is this not supported on windows? __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
