[R-pkg-devel] Unable to reproduce reported problems. Docker image?

[Borini, Stefano]

I think (but I am not sure) that I narrowed down the issue to a stochastic process that has no seed defined. Unfortunately it's not my package so I have to do mostly guesswork on this regard.
What has surprised me though, is that I managed to get exact same results on three different platforms (linux, mac, windows) and three different versions (3.4, 3.5.3, and development), but the only platform that shows the variation is the CRAN one. Only when I added a single throwaway sample() call I got the same behaviour on my machines.

Thank you for your help.

    it probably makes sense to more directly indicate what package is causing problems (e.g., sharing the location of a public repository of the source) and the nature of the error (cut-and-paste the check output here?). Likely this will lead both to insight into the problem being flagged by the builder, and the reason why you are not able to reproduce it.

        | Thanks. What is the recommended strategy in this case? Keep submitting and patching until it passes?

        Standard debugging, and (as Uwe already said) win-builder for that OS, rhub
        for others, and asking here, ...  Imperfect, but doable.

        It would be so nice to have actual Docker containers to reproduce issues.
        Maybe one day.
