Not saving the session won't help if the previously saved session
(still containing the broken .Random.seed) still lingers around.
So the fix is to start a fresh R session without restoring the
previous workspace (e.g. ``R --no-restore''), and then saving
that. This will lose all previously created stuff, though (which
is something to be aware of in case the workspace contains some
precious unsaved data).
Alternatively, if you run
rm(.Random.seed)
the ``runif(10)'' call will work again (and create a new .Random.seed
of the right type as a side effect). Then when you quit, do save
the workspace to fix the problem "permanently".
Generally, I recommend disabling automatic saving and restoring of
workspaces, e.g. by aliasing R to ``R --no-save --no-restore'',
and using the save and load functions explicitly where needed;
I've seen (way too) many workspaces that have accumulated phenomenal
amounts of clutter and generating quite a share of "mysterious"
failures and irreproducibilities caused by this auto-save
mechanism.
