R help - Nov 2008 - Set of standard city size symbols as known from atlases?

Hi,

I am wondering exists a standard set of symbols to mark cities of different size
classes on a map for R yet?

In a standard atlas there are symbols like small filled circles, small filled
circles with an outer circle, same with small squares, etc. which mark capitals
and different size classes of cities.

I know I can get different symbols with the pch option in plot but the question
aims at if such more standard symbols of atlases are available.

Many thanks,
  Werner

I don't know of an existing set of symbols for this, but if you can come up
with a set or descriptions of what you want, then the my.symbols function in the
TeachingDemos package can be used to place them on a plot.
