[R-pkg-devel] Puzzling error from win-builder
Without thinking about it very much, my first guess would be that this is a transient problem on win-builder, i.e. the caret package is temporarily unavailable for some reason (e.g. because some update step hung); a new version of the package was published *fairly* recently (2021-05-15), although I would find my explanation more compelling if the update was more recent (and if the CRAN page for caret wasn't showing that the Windows binaries have all been updated to the current version). As a hackish way to explore this further, you could find a different CRAN package that depends on caret, edit the DESCRIPTION file to substitute your e-mail address as maintainer, and submit it to win-builder (if you don't edit the DESCRIPTION then the package maintainer, not you, will get the e-mail saying that the build is done; I don't know if this is allowed by win-builder rules but even if not it seems like a minor transgression).

I have a puzzling error from win-builder for a package. My package is https://github.com/jonathan-g/datafsm, also https://cran.r-project.org/web/packages/datafsm. I am preparing a bug-fix release to CRAN to fix an error that CRAN recently identified in the previous release of this package (see https://cran.r-project.org/web/checks/check_results_datafsm.html). The package passes R CMD check with no errors or warnings, and one note (harmless) on win-builder for R-devel (https://win-builder.r-project.org/8mp9LN00YVw4/00check.log) and R-oldrelease (https://win-builder.r-project.org/1K21X458WtYt/00check.log), but for R-release, win-builder has two errors in running tests and building a vignette (https://win-builder.r-project.org/exK86Fkyir2s/00check.log), all of which say the CRAN caret package is not available for Windows x64:

My package declares the "caret" package as an import in DESCRIPTION, so I am puzzled what this error from win-builder means and how to fix it. If R CMD check got this far, and installed the package for testing without reporting missing dependencies, why is it suddenly unable to use the caret package for testing the package, but only for the x64 architecture? Is this something I am doing wrong, or is it a bug in win-builder? Is anyone else finding problems with win-builder reporting errors about CRAN packages not being available? For what it's worth, the package passes R CMD check with no errors or warnings or notes under GitHub actions (Windows, MacOS, and Ubuntu), on rhub (Debian, Fedora, Ubuntu, MacOS, and Windows except for R-devel under Windows, where R CMD check fails with a message about BioConductor not having binaries for R 4.2, even though my package doesn't use any BioConductor packages), and on my local Windows and Ubuntu boxes, so this seems to be a problem specific to R-release under win-builder. If anyone has any suggestions for how I can fix this problem and submit the new release of my package to CRAN, I would be grateful.
