Hi R-help: I'm just an old guy and new to this list... But have been using R for years now. I want to make a map of counties in the US with shaded colors that depend on the level of variable "Y" that I want to map. I have the US county and state fips codes and the Y variable. How do I do this? Please reply to pzs6 at cdc.gov Thanks, Phil Smith pzs6 at cdc.gov
