[R] heat map - how to import a graphic?

2011-11-28 Thread alison korte
If I want to create a heat map where I have a graphic of a US State with county borders, how do I import and work with the graphic image? The reason I would like to use R is so I can then define color parameters and quickly produce heat maps that correspond to various data in dataframes.

I suggest you post this on the R-sig-Geo list rather than here. -- Bert On Mon, Nov 28, 2011 at 10:22 AM, alison korte amingko...@yahoo.com wrote: If I want to create a heat map where I have a graphic of a US State with county borders, how do I import and work with the graphic image? The
