I was wondering if there was a map of the US similar to the usa() map in Splus? If anyone knows of one, or how to convert the Splus usa() map for use in R, I would greatly appreciate hearing from you.
You don't say which platform or version of R you are using (it often matters, and the platform does in this case). There is a maps library for S, distributed with S-Plus. I have ported most of that to R. It is available for Intel/Linux or SPARC from: ftp://ftp.mcs.vuw.ac.nz/pub/statistics/map/ in files maps_0.1-9_*.tar.gz. These are R packages, which include map databases for usa, world, china and nz (hence the 25MB size). Note that thinning is not implemented, and projections have some problems, you are welcome to try and sort them out. Hope this helps, Ray Brownrigg -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
