Neat. Things you might like to do include: 1. Adding a background image, either OpenStreetMap via my "webmaps" package, or get Ordnance Survey raster data. You may have to transform from lat-long to OSgrid ref, but that's all in the spTransform package. 2. Make a web-based animation like this: http://www.maths.lancs.ac.uk/~rowlings/Chicas/WeeklyCJejuni/ using my animation framework: http://www.maths.lancs.ac.uk/~rowlings/Chicas/DIY/ 3. Check out the Spatial Task View on CRAN and get to know the packages: sp, spTransform, rgdal, raster. 4. Show us your code?
I'm loving learning R. Very cool. I'd like to use it for some proper analysis though (epidemiology or something), instead of tweet maps. :)
Maybe if you mapped every tweet that mentioned the word 'sneeze' you'd get the epidemiology of the common cold - not quite as ridiculous as it sounds: http://www.google.org/flutrends/ Barry
