From R 4.0.1 forward, --slave is deprecated: https://cran.r-project.org/doc/manuals/r-release/NEWS.html

-s is an undocumented alias for the flag formerly --slave now --no-echo and thus ensures backwards compatibility. Alternatively, going forward, we could trap for the R version to be called and choose -s or --no-echo as needed.
