Erin, If you look at <http://cran.r-project.org/web/views/Spatial.html> you'll find a compendium of packages for various spatial statistical analyses. Most packages come with data sets. You'll definitely find something to your liking there. Rich
Try the quakes data in package datasets:
data(quakes)
head(quakes)
lat long depth mag stations
1 -20.42 181.62 562 4.8 41
2 -20.62 181.03 650 4.2 15
3 -26.00 184.10 42 5.4 43
4 -17.97 181.66 626 4.1 19
5 -20.42 181.96 649 4.0 11
6 -19.68 184.31 195 4.0 12
Cheers, Mike.

I'm using simulated data but thought it would be nice to try with a regular set. Thanks, Erin Erin M.

If you want something that's literally up-to-the-minute then try the USGS real-time earthquake data, available in CSV format so you can just read.csv-it directly. Various ones listed here: http://earthquake.usgs.gov/earthquakes/catalogs/ > require(sp) > url="http://earthquake.usgs.gov/earthquakes/catalogs/eqs1day-M1.txt" > q=read.csv(url) > coordinates(q)=~Lon+Lat > plot(q) you get the depth and magnitude of the quake, as well as the "NST" but I don't know what that is...

In the TeachingDemos package there are 3 datasets 'ccc', 'h2h', and 'towork' which are real, not overly large (but you can decide if they are small or not) which contain lat, long, and other variables.

Sorry for cross posting You can check also the asdarbook website or the cran of different packages they have really nice data. Juan Sent on the Sprint?
