R, maps, choropleth, data keys
...5. I have carefully followed a number of tutorials and can reproduce those, and can also produce scatter and bubble plots of my data (using long and lat coordinates to place the pch and bubbles). What the tutorials (apparently) don't cover is how to key the data with the shape files to produce choropleth maps. My keys for states are like AK, AL, AR, etc., and my keys for the zip3 are like 902,303, 465, etc. The examples seem to use data that's part of the shape file (such as POPULATION), but my data is in separate files. How do I connect the ID in the shape files with the key in the data files?...

Consulta mapas
Hola! Quiero empezar a georeferenciar en mapas con R. En blogs se encuentra bastante información pero veo que no hay unanimidad respecto a las librerías a utilizar ni tampoco la información es muy clara ni abarcativa. ¿Alguno/a trabaja con mapas en R y me puede indicar por donde encarar? En principio mi interés es realizar mapas sencillos con información por provincias y departamentos de

heat map - how to import a graphic?
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.   Thanks.

Maps in R
Apologies in advance from an R newbie if this is a dumb question. Is it possible to produce choropleth maps in R? I gather from some nice research papers on the AT&T (sorry, Lucent) S web site that in S (and S Plus) there is a map() function which uses arrays of polylines and regions to draw map borders and then fill them with patterns or shades according to some scalar quantity. We currently pr...

[lattice] how to overlay a geographical map on a levelplot?
...is somewhat geospatial, so I posted to r-sig-geo rather than here: https://stat.ethz.ch/pipermail/r-sig-geo/2012-November/016757.html > summary: How to overlay a geographical map on each panel in a lattice > (or Trellis), e.g., of levelplot's? Note I am not inquiring about > creating choropleth maps[,] which Sarkar 2008 covers quite well (and which is supported by latticeExtra::mapplot): I just want to appropriately overlay a garden-variety boundary-line map on panel viewspaces defined by longitude and latitude. A relatively small, quite self-contained example follows the quote above, i...

library maps for R
Anybody interested in the S maps library for R? I have ported a limited version of the software for a Unix platform, and would be happy to make it available for anybody interested. If there is a lot of interest then I will submit it to CRAN. I know that Ross Ihaka is working on a new version for R, which does not have some of the limitations of the original S version. My version does not do
