Dear all, we faced a warning on r-oldrel-macos-x86_64: https://cran.r-project.org/web/checks/check_results_PowerTOST.html I'm not concerned about "Pandoc (>= 1.12.3) and/or pandoc-citeproc not available" in the first 5 vignettes since there were no problem in the previous releases. However I found this on stackoverflow: https://stackoverflow.com/questions/50789125/how-to-get-an-rmarkdown-vignette-for-r-package-to-escape-cran-warnings-on-solari RolandAsc commented: "In my understanding you can only see this warning if there is an error (either because warnings are being converted to errors or because there is another subsequent error), else it just doesn't come through. This is not an answer but maybe an explanation." Seems to be correct. In my code a data.frame is assigned with a column "foo" and _without_ stringsAsFactors = FALSE. Later a function is called which requires "foo" as character. The default stringsAsFactors was changed to FALSE in R4.0.0. Hence, my question: How "old" is the old releaseon CRAN's test machines/ macos? oldrel on windows is OK. What shall we do? Re-submit with the same release-number(either add stringsAsFactors = FALSE or call the function with as.character("foo")with an explanation?
By not specifying stringsAsFactors = FALSE, your vignette depends on R >= 4.0.0, so you should - state that dependency in the DESCRIPTION file, or - test for it in the vignette, or - remove the dependency by being explicit about stringsAsFactors = FALSE. Duncan Murdoch
