Hi Jan, To add to the suggestion of Gabor and Duncan, it might be a good idea to add a packageStartupMessage that warns the user about the problem when running on a 32bit system. You can easily extract that info from R.Version()$arch . That might help negotiating with CRAN.

Let me make this more clear. The R package reticulate works on 32bit and 64bit. My golgotha package depends on reticulate and an extra Python package called torch which is not available for 32bit platforms. This is specified in the DESCRIPTION file at https://github.com/bnosac/golgotha/blob/master/DESCRIPTION#L17 For that reason R CMD check will fail on CRAN for 32bit. Hence my question. How do I specify this in the package such that I can distribute it on CRAN. best, Jan Jan Wijffels Statistician www.bnosac.be | +32 486 611708 ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Monday 11 May 2020 14:39, Duncan Murdoch <murdoch.dun...@gmail.com> wrote: > On 11/05/2020 7:54 a.m., Jan Wijffels wrote: > > > Hello everyone, > > I have a package which I would like to host on CRAN.
