[R-pkg-devel] Fwd: Reproducing CRAN pre-tests

[Aravind J.]

Hi,

I was able to fix the issue and submit my package successfully to CRAN.

However, the question remains, is there any way to replicate the CRAN
pre-tests locally for future debugging, particularly in a windows
environment?

I had tried rhub platforms without any success.

Warm Regards
