Dear Rers, is there a way to color counties on a full US map based on a criterion one establishes (i.e., all counties I assign the same number should be the same color)? I explored a bit and looks like the package "maps" might be of help. library(maps) One could get a map of the US: map('usa') One could get countries within a US state: map('county', 'iowa', fill = TRUE, col = palette())
Would it be possible to read in a file with counties and their assignments (some counties have a 1, some counties have a 2, etc.) and then have one map of the US with counties colored based on their assignment? Thanks a lot for any hint! -- Dimitri Liakhovitski ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
