I would strongly suggest you take another look at some of these
packages (especially QGIS).
These are relatively young projects, and are growing
Hello all,
An alternative to create (possibly simple) shapefiles is the
"shapefiles" package.
http://cran.r-project.org/web/packages/shapefiles/index.html.
Also the "PBSmapping" package is a very good alternative to make maps
within R, and to perform basic GIS operations (i.e. overlap of poly

I'd go with the shapefiles, the E00 files are ArcInfo export format
files, and it is very likely you would convert to shapefile sets along
the way.

Tom,
Er, what exactly is your data? Do you have data that is linked to zip
codes and you want to do a "thematic" (choropleth) map of the data? Do
you have point data (say a lat/lon values), and want to plot the points?
Given what you've said, hard to figure out how to get you going in the

I think you should look at the cross-variograms. Or did you already

I have limited experience with spatial analysis, but I am trying to learn.
Perhaps someone with patience for a newbie will field my questions? If this is
not the appropriate forum for such questions perhaps someone could suggest a
more appropriate forum.
