[R] elevation map with R

[R] Coloring Counties in a State Map

I am mapping U.S. state counties in individual states maps, e.g. A map of Montana, with county lines. How do I fill specific counties with a different color? -- View this message in context: http://r.789695.n4.nabble.com/Coloring-Counties-in-a-State-Map-tp4638218.html Sent from the R help mail
