You can't.  We'll treat that as an enhancement request.  It's actually a
per-device switch, so it could be part of the windows() function
arguments.

Use .Rprofile. See ?Startup

It can be specified for lots of modelling functions.  Beware though, that
what `weights' means needs careful definition, and Stata (I believe)
manages to have four kinds of weights.  In regression weights=4
could mean `I have four of these cases' or `give this case weight 4
in weighted LS', for example.  Fortunately in regression it rarely
matters, but it can do in other settings.
