I absolutely agree. While I've solved the issue for myself long
ago by always putting something like
alias R='R --no-save --no-restore'
into my startup scripts (~/.bashrc or the like), I've seen too many
others caught out by implicit saving / restoring of workspaces (e.g.
by somehow just accepting that R "only works properly in this particular
directory" and therefore doing all their work there at the cost of
adopting various anti-patterns with respect to organising work into
directories.
Personally I think that auto saving / restoring workspaces should
be reviewed, as it can, in practice, make it harder for people to
render their work in a self-contained and reproducible way.
