Hi,

The following will make f inherit all options of Plot and the default
values that are set at the time this is executed:

Options[f]=Options[Plot]

Test:

f[OptionsPattern[]]:=OptionValue[Ticks]

f[Ticks->None]

One could try to use SetDelayed (:=) so that the defaults for f's
options reflect the current settings of Plot, but this works only until
one does a SetOptions[f,...]. To make the behaviour more consistent in
that case would require some extra work...

hth,
