it's dangerous to fit a model that includes interaction effects but omits

Your any-RDS-to-ASCII-converter could be the R function
toASCIIRDS <- function (fromRDS, toRDS)
{
saveRDS(readRDS(fromRDS), file = toRDS, ascii = TRUE, compress = FALSE)
}
which you can call from Rscript with appropriate input and output file names.

Thanks for the input Jeff and Burt, and I could have been more clear about

You are of course right that there is nothing preventing me from using
plain text files, I initially went with compressed binary files because
they were, of course, smaller.

You are sending contradictory signals... do you or do you not want plain text
files? You have not indicated what advantage you are getting from having
binary files in your repository. By far the best answer I see to your dilemma
is to save in ASCII format instead of the default binary format.
Try looking at your function and work through what happens if the length
is what I suggested.

So unless m1 has length at least x you are doomed.
