[R-pkg-devel] Excessive time of first example to be checked

[Guido Moreira]

There's an useful tool for testing in Windows.
Check out https://win-builder.r-project.org/ where you can upload your
tarball and have it built on Windows and give your R CMD check --as-cran
results. Also, you can use github actions to automatically run R CMD check
--as-cran when you push to your repo.

This may not help you directly root out your problem, but it should be
quicker to get check results than uploading to CRAN and using their
resources.

Cheers!
