I have had success by downloading the zipcode (approximate) shapefiles (the .shp files) from: http://www.census.gov/geo/www/cob/z52000.html

Then using the maptools package (rather than the maps package).

hope this helps,

i've search the email archives, searched the documention of various map packages and done an R-site search, but have been unable to find direct resources for creating maps of the US that are colored or annotated or ... by zipcode data.

For example, create a map of the US and color each zipcode region by its population using two vectors z,p containing the zipcode and population, respectively. I'm not looking for data to fill z, and p. I'm looking for some highend functions to display on a map the data that I already have.

Cheers,
Mike
