Hoi Martin,

Thanks for helping. This also works for me, but not if I put
R_BATCH_OPTIONS="--no-restore --no-save" in ~/.Renviron.
If I have an R script called MWE.R containing
print(Sys.getenv("R_BATCH_OPTIONS")), I correctly see "--no-restore
--no-save"
being printed to .Rout, but still obtain .RData. (I also think this is
a macOS problem, but couldn't figure it out yet).

Cheers,
M
