I am trying to create a map with selected states based on highest to lowest mean cost. The following code properly selects the correct states, and the legend is properly color coded with ranges, but the colors per range does not match the state colors. I need help getting the state colors to match the ranges outlined in the legend. I have tried ordering the mean amounts and this correctly creates

...dows Vista 64-bit. I have no experience working with maps, but now I have to plot a map of Denmark in which each Danish county is color-coded according to its incidence rate of a particular disease. My problem is that I don't know where to start. I have read the help files to packages like 'mapplot', and their examples indicate that I am on the right track, but where do I find a suitably detailed map of Denmark, and which format should I prefer? The terminology in the help files etc. is overwhelming. Thank you in advance for any help. Best regards, Peter. *** R version 2.8.1 (2008-12-2...

A relatively small, quite self-contained example follows the quote above, in which I plot toy data in the sort of lattice layout I need ... except that each panel lacks...

Is there a way to generate maps in R. Specifically, I have calculated estimates of intra-regional inequality for US states, and would like to project that information onto a map. Thanks, Nirmala

Hi, I am looking for a way to plot bar on a map instead of the standard points. I have been using ggplot2 and maps libraries. The points are added with the function geom_point. I know that there is a function geom_bar but I can't figure out how to use it. Thank you for your help, Simon ### R-code library(ggplot2) library(maps) measurements <-

Hey R'rs, So im sick of dealing with ESRI products and am looking to stream line a process i now use GIS to do using R. I have made a lot of maps using R but have not yet seen a map that puts pie charts within the map to help represent data like the attachment. http://r.789695.n4.nabble.com/file/n2318816/template1.bmp I found Tanimura et al. work "Proportional Symbol Mapping in
