Dear All,
 
wondering if anyone could help with a working code for the following:
 
I would like to plot a map using R that includes New York City (with counties of Kings, Queens, Bronx, New York and Richmond), Westchester, Nassau, Suffolk and Rockland counties (any color would be ok per county as long as they are different), and place 4 visible red dots at the following zip codes: 11219, 10960, 10003, 10029. Can this be done in R?
 
thank you,
 
Andras
